Using input variables such as embankment height, geological condition and soft soil thickness, the FRBDS evaluates the ground treatment level, based upon which the highway engineer determines a suitable treatment method taking into account project constraints. In the case study, the FRBDS is applied for a 10-km package of HaNoi–HaiPhong expressway construction project and is evaluated in comparison to expert judgements. The results show that the treatment methods provided by the two approaches are similar for 36 out of 52 sections of the package, but the FRBDS provides more consistent and rational solutions. In particular, the FRBDS significantly reduces technological fragmentation. It can be concluded that the FRBDS is a useful tool that establishes structured innovative solutions to improve the quality of decision-making for large transportation projects.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":"17 1","pages":"298 - 309"},"PeriodicalIF":1.9,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48324663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel numerical model supported by a set of experimental observations has been considered to capture pile-soil interaction for the pile groups subjected to torsional load. The torque mobilization, progressive twist, and displacement have been computed for a range of the initial shear modulus ratio for the entire set of pile groups. As a result of twisting, the torsional energy zones are set into the soil, and there is the formation of a heave and cavity around the pile group. The torsional energy and twist rigidity parameters were evaluated for a range of shear modulus ratios of the soil. It has been observed that the torsional energy of the pile group (1,2) is significantly higher than pile groups (1,3; 2,2). A classification for torsional energy zones associated with twist rigidity and displacement rigidity factor has been suggested to set the limits for twist and displacement of the pile groups relative to a single pile. A relationship of the torsional energy with progressive twist and displacement is obtained.

This study modelled the non-uniform ground movements (or non-uniform ground loss) around the tunnel cavity using the Gaussian distribution function. A new approach is proposed to model the tunnel peripheral displacements other than the simplistic trigonometric functions. It is shown that by modelling the ground loss in an elliptical fashion, (i) better prediction of ground surface settlements is obtained compared to the circular ground loss in some cases, while (ii) in other cases, circular ground loss gives better predictions. This indicates that both these approaches should be used to predict the ground surface settlements. Further, the ground displacements observed in East-West Metro, Kolkata, are discussed as a case study. The semi-analytically obtained displacements give good conformity with the observed field measurements in East-West Metro. This solution is much simpler to follow and can be easily employed in a code compared to the complex variable method or airy stress function method.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":"17 1","pages":"320 - 329"},"PeriodicalIF":1.9,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46624875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also effective in enhancing plant performance. However, how biochar affects the soil heavy metal toxicity considering the plant–soil interactions is not well summarized. Therefore, this paper aims to review and summarize the effects of biochar on heavy metal availability in vegetated unsaturated soil. First, this review summarizes the effects of biochar on key parameters of unsaturated soil, including pore size distribution, water permeability, water retention curve, nutrient cycling and soil biota. Then, the mechanism of biochar for managing heavy metals in soil with vegetation is discussed, with a focus on both physical and biochemical aspects. Additionally, the impact of biochar-induced plant growth on the availability of heavy metals in the plant–soil system is explored. Finally, suggestions for future research and applications of biochar are provided. This paper supplies novel outlooks for further study and practice.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":"17 1","pages":"260 - 270"},"PeriodicalIF":1.9,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48257935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Homogeneous sand slopes with four slope geometries, namely, normal surfaces, curved surfaces, turning corners and turning arcs of various angles and slope inclinations, were analysed using PLAXIS LE. The 3D results demonstrated that the factor of safety of curved surface slopes will decrease with increasing concave curvature. For turning corner slopes, an increase in the concavity resulted in an increase in stability. When comparing the 3D and 2D results, the analysis showed that while most of the 2D analysis results yield a lower factor of safety than that of a 3D analysis, there were various concave slopes in which a 3D analysis was more conservative. The study also demonstrated that a 3D analysis is beneficial to capture slope failures spreading across the sloped surface, which can be used by practitioners to design more cost-effective stabilization measures.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":"17 1","pages":"271 - 282"},"PeriodicalIF":1.9,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59987506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three commonly used sampling techniques, namely, pseudo-random, quasi-random (QR), and Latin-hypercube sampling (LHS), are investigated to determine the efficiency of each sampling technique for sensitivity analysis and identify the critical parameters for the soil model. Among the sampling methods, LHS shows the best sampling uniformity and offers more stable results and faster convergence than other methods. The analysis results also show that Young’s modulus and the initial value for the shear-yield surface are the most critical parameters for the designed outputs, which quantitatively measure the maximum total deformation (MD), plastic deformation (PV), and plastic zone size (VY).

A three-dimensional finite element analysis using PLAXIS 3D was conducted to examine the effect of various factors, including anchor shape, embedment depth, and the presence of a groundwater table, on the pullout resistance of anchor blocks. The results showed that anchor shape affects the pullout resistance, particularly for anchor blocks with small aspect ratios. The presence of groundwater table between the ground surface and the base of the anchor block affects the pullout resistance of the anchor block. Based on the results, an empirical correlation was developed to account for the effect of the groundwater table on pullout capacity. The study also compared different pullout capacity prediction models with the results of the numerical simulations for varying embedment depth ratios.
