A significant challenge in the field is the accurate and interpretable assessment of large-scale landslide hazards, particularly due to the lack of consideration for the synergistic effects of multiple triggers and spatial heterogeneity. This study introduces a novel regional hazard assessment method that leverages geographic similarity to address these challenges. Our approach consists of four key steps: (1) extraction of sample information from relevant data based on the historical distribution of landslides and their influencing factors, (2) application of a scale-space algorithm to manage spatial heterogeneity, with a partition scale determined by the q-value variation, (3) optimization of sample configuration and generation criteria under the guidance of geographic similarity for enhanced spatiotemporal modeling, and (4) utilization of machine learning models to refine inductive bias and capture nonlinear relationships, enabling a quantitative estimation of hazard probabilities for each slope unit within the prediction module. We applied our P-RF + method to Yunnan Province, China, incorporating 11 condition factors and 7 trigger factors across 624 historical rainfall-induced landslides and 1248 non-landslide cases. Comparative experiments reveal that the P-RF + model substantially outperforms existing methods in accuracy and interpretability. Furthermore, a case study during the rainy season illustrates the model's capability to provide timely warning instructions for rainfall-induced landslides. These findings underscore the potential of our proposed method to offer valuable insights for disaster prevention decision-making.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"83 12","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10064-024-04001-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to compare the value of sliding friction angle obtained from direct shear tests on rock fractures and that obtained from triaxial compression tests on intact rock cores. For this reason, 286 direct shear tests were carried out on artificial rough tension fractures of ten different rock types under normal stresses 5 kPa − 2 MPa, using the multistage shear procedure with repositioning of the joint before each shearing. Another 112 conventional triaxial compression and unconfined compression tests were carried out on NX size (54 mm) intact specimens from the same rock types under various confining pressures up to 70 MPa. The sliding friction angle from the direct shear tests was determined from the measured peak friction angle and the corresponding dilation angle and that from the triaxial compression tests from the stress state at the estimated brittle-ductile transition. The results show that the values of the sliding friction angle of the studied rocks determined by the two methods are approximately equal (differences < 1°) and agree very well with well-established experimental data for similar types of rocks reported in the literature. They ranged between 32.5° and 40.2° with those of the weaker and more ductile carbonate rocks to be distinctly higher (35.4°-40.2°) than those of the stronger and more brittle silicate ones (range 32.5°-35.6°).

Lower initial water content and higher vertical load are more effective in suppressing cracking during the desiccation of compacted loess. The surface crack ratio (R<sub>sc</sub>) of compacted loess is reduced by 99.54% as pressure increases from 0 to 100 kPa and water content decreases from saturation to 5%.

The creep deformation of the LQ landslide occurred continuously during the period of meteorological rainfall concentration. Natural rainfall was the main triggering factor of the long-term creep deformation of the LQ landslide. With increasing saturation degree and time of the slide zones, the creep deformation of the LQ landslide was caused by weakening of the shear strength and expansion of the slide zones, causing cracks in roads and houses built on surfaces. When the natural rainfall decreased, the weakening, softening, and expansion mechanism of the slide zones weakened. The stability of the LQ landslide increased, and the creep deformation gradually stopped.

In this study, the permeability and microstructure of sodic-saline loessal soil with different initial water contents (IWCs) and salt contents (ISCs) obtained from pre-saturation and subsequent drying were explored using constant head permeability tests and SEM observations. The results show that the permeability coefficient decreases exponentially with time.

The microscopic results show that during the seepage process, the porosity and pore diameter of samples with low IWC gradually decrease, accompanied by a weakening of pore directionality and an increase in fractal dimension. In contrast, samples with high IWC show an initial increase followed by a decrease in porosity, pore diameter and pore directionality, alongside a gradual decrease in fractal dimension. The drying process promotes the formation of inter-aggregate pores and weakens aggregate stability, leading to significant microstructural disturbances in low IWC samples upon rewetting. The increase in salt content enhances particle cementation but also creates additional channels for rapid permeability.

This paper proposes a novel hybrid intelligent prediction model to enhance the prediction accuracy of point displacement in reservoir landslides and construct reliable displacement prediction intervals. Specifically, PSO-SVM is adopted to predict the trend displacement, while CNN-GRU-Attention is designed to predict the periodic displacement. Furthermore, the hybrid model allows for the direct construction of required displacement prediction intervals based on the landslide time series. The superior performance of the proposed model is proven by using the Baishuihe and Shuping landslides as case studies. The results demonstrate that the developed model achieves higher prediction accuracy and enables the construction of reliable displacement prediction intervals. Additionally, the proposed model can predict the time series of unknown displacement and provide an early warning of landslides at the early stage of displacement mutation.
