Here, different considerations have been made regarding the temporal and spatial variation of these BCs to assess their effect on slope behaviour. Specifically, daily and monthly atmospheric data were contrasted, dynamic vegetation growth was juxtaposed with static vegetation, and water extraction with depth due to transpiration was compared with a simplified approach where evapotranspiration was modelled to occur from the ground surface. A representative cut slope was considered, and fully coupled hydro-mechanical analyses were conducted under different BCs to study its stability and serviceability. The numerical results highlight which modelling choices significantly influence predicted performance, particularly under climate change, and which can be safely simplified.

{"title":"Effects of Cementitious Amendments on the Mechanical Strength and Hydraulic Conductivity of Mine Tailings for Reclamation Cover Systems.","authors":"Audrey Jalce, Isabelle Demers, Benoit Plante, Thomas Pabst, Eric Brouard","doi":"10.1007/s10706-026-03853-9","DOIUrl":"10.1007/s10706-026-03853-9","url":null,"abstract":"<p><p>Tailings storage facility (TSF) reclamation commonly involves the construction of cover systems, requiring large volumes of materials with specific hydro-geotechnical properties. When suitable materials are not locally available, their extraction and transport can generate significant environmental and economic costs. On abandoned or inactive TSFs, where long-term acid mine drainage may occur, reclamation is highly sensitive to geochemical conditions, especially for weathered tailings affected by indirect oxidation and secondary mineral precipitation. Using these tailings as cover materials represents a promising alternative but would require improvement of their mechanical performance and limitation of metal leaching. This study investigated the effectiveness of general use limestone (GUL) and slag-based cements, a combination of GU and ground granulated blast furnace slag (GGBFS), for the solidification/stabilization of weathered tailings to create a hydraulic barrier. Cemented paste mixtures incorporating 5-7 wt% binder were evaluated through unconfined compressive strength (UCS), saturated hydraulic conductivity (k_sat), and mineralogical analyses. The addition of binder significantly increased mechanical strength and reduced k_sat, with UCS > 1000 kPa and k_sat < 1 × 10^-9 m/s, generally achieved after 28 days of curing with 7 wt% binder. Performance depended on tailings geochemistry: slag-based cement (20GU/80GGBFS) performed better in tailings with neutral paste pH, while GUL yielded higher UCS in acidic tailings. Very limited hydrate formation was observed: mainly ettringite in GUL-treated sulfate-rich tailings and C-S-H in slag-treated mixtures. These results demonstrated that cementitious treatment of TSFs could be an efficient, if binder type and dosage are adapted to site physical and geochemical variability of weathered tailings.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10706-026-03853-9.</p>","PeriodicalId":48246,"journal":{"name":"Geotechnical and Geological Engineering","volume":"44 7","pages":"353"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13503432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148819884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The state-of-the-art mainly focuses on the effect of heterogeneous properties within a layer on engineering problems. From this, it is known that the variation in properties can increase the vulnerability of a structure. However, nearly always variations in the soil lithological conditions are disregarded, while they can influence subsidence potentially even more. Lithological variations are relevant both at the scale of individual buildings as well as different scales (city, regional, country), for which often detailed soil information is not available. Thus, for a better prediction of potential building damage related to subsidence, knowledge about the scale and influence of lithological variations is needed. This paper describes an approach to quantify and investigate the influence of lithological heterogeneity at the scale of a single building. Moreover, this exploratory study evaluates the influence of lithological heterogeneity on the spatial variability of settlements, intending to upscale the approach to regional application. Two independent datasets at high resolution (site-specific) and low resolution (national level) are used to retrieve the stratigraphic conditions for the area selected for the analyses. One-, Two- and Three-dimensional numerical models, based on the collected information are used to simulate the consolidation process and settlement due to a uniform load imposed on the surface level of the study area. Additional analyses investigate the influence of loading conditions and groundwater table. The parameter \"correlation length\" is used to quantify the spatial variability of the soil layer thickness and then of the computed settlements. The analyses reveal that the spatial variability of the soil strata thickness matches that of the computed settlements, ranging from 2 to 10 meters. In other words, the lithological variability of the soil leads to differential settlements occurring at the scale of man-made structures such as houses, roads, and embankments. Thus, the results encourage including the contribution of lithological heterogeneity in models and predictions of differential settlement at the scale of individual structures. Moreover, the statistical properties, in terms of mean, spread and distribution shape, of the settlement computed through in-situ specific models, match with those derived at the national scale. These results are expected to support the identification of areas potentially influenced by lithological soil heterogeneity, thus showing potential for upscaling to regional or national levels.</p>","PeriodicalId":48246,"journal":{"name":"Geotechnical and Geological Engineering","volume":"43 5","pages":"206"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122620/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A finite element model is developed using parameters derived from a representative Dutch dike case (Bergambacht), incorporating the Hardening Soil, Soft Soil Creep and NGI-ADP-SHANSEP models to capture soil behaviour. Pile installation is simulated through the application of lateral volumetric strain, with varying pile diameters, spacings, and locations within the dike profile. The equivalent diameters used in the analysis range from 10 to 40 cm, corresponding to pile walls with diameters between 25.5 and 100 cm when the spacing equals the diameter. The pile wall location varies from the dike toe up to 21 m away, which is at the outer crest, with a varied length reaching -12 m NAP. A two-storey building on deep pile foundations is included to assess the effect of installation-induced displacements, with its location ranging from 5 to 20 m from the dike toe. Results show that positioning the pile wall within the inner slope offers the best balance between increased factor of safety, reduced required pile length, and acceptable levels of deformation. However, the installation process can generate significant horizontal displacements, particularly near the dike toe, which may compromise adjacent structures. The study finds that displacement piles are unsuitable within 10-15 m of existing buildings unless smaller pile diameters or alternative installation methods are used. Soil stiffness and installation-induced stresses also play a key role, highlighting the importance of site-specific assessments and careful design calibration using field data.</p>","PeriodicalId":48246,"journal":{"name":"Geotechnical and Geological Engineering","volume":"43 8","pages":"446"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12454509/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing approaches of regional liquefaction hazard assessment predominantly rely on deterministic analysis methods. This paper presents a novel Probabilistic Liquefaction Hazard Analysis (PLHA) framework based on Monte-Carlo (MC) simulations to mitigate future seismic risks associated with liquefaction. The proposed procedure requires only publicly available data, offering accessibility and applicability in resource-constrained settings. A key feature of the procedure is its ability to deal with uncertainties in earthquake and soil parameters using distribution functions.

The procedure is implemented in MATLAB as part of a broader probabilistic risk assessment framework for developing countries. The developed procedure is applied to the high risk city of Adapazari, Türkiye; an area lacking prior PLHA studies.
