In Bangladesh, mountainous areas such as Bandarban experience significant landslides during the monsoon season. This study seeks to evaluate landslide susceptibility in Bandarban and identify hotspots for optimal landslide hazard mitigation. This study examined landslide susceptibility using the analytical hierarchy process (AHP) and spatial weighted overlay (SWO). Ten conditioning factors were considered, with AHP based on responses from 100 key respondents. Using field surveys and high-resolution satellite images, 280 landslide occurrence samples were collected to rank the subfactors. Using AHP-derived weights of factors and subfactors, the SWO approach was used to create the landslide susceptibility map (LSM). The Getis-Ord (<em>Gi</em>∗) spatial statistics was then used to generate landslide susceptibility hotspots. The result showed that human influence weight 17.02%, making it the most crucial factor in landslide susceptibility. AHP-derived weights were reliable because their consistency ratio was &lt;0.1. According to the study, 59.86% of the area is moderately susceptible, 20.06% is high, and 4.31% is very high. The validation of LSM by ROC curve found excellent performance (AUC ​= ​0.93) of the approaches. Specifically, 63.8% of very high susceptibility areas and 33.26% of high susceptibility areas were found within the hotspot zones with 99% confidence. The research showed the combined use of field samples and remote sensing-based spatial variables improved the accuracy of LSM. These findings can be useful for ensuring proper land use planning and implementation of landslide hazard mitigation measures.</div></div>","PeriodicalId":100580,"journal":{"name":"Geohazard Mechanics","volume":"3 4","pages":"Pages 272-285"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145765870","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}

Permeability coefficients and the radii of permeability ellipses are calculated at 30-degree intervals along the network, enabling comprehensive evaluation. Utilizing the least squares method, seepage ellipses are fitted to determine primary seepage coefficients. In consideration of the most unfavorable scenarios, rock mass seepage coefficients are selected for grouting design calculation. For each grade of surrounding rock mass, assessments are conducted to ascertain the water inflow of unlined tunnels, the water inflow of lined tunnels, and external water pressure on tunnel linings. Tunnel curtain grouting is required when the tunnel water inflow exceeds the design limits. Appropriate parameters for grouting ring thickness and permeability coefficients are selected to fulfill engineering specifications. In cases of excessive external water pressure in tunnel linings and significant inflow of water into the tunnel, it is recommended that grouting and lining operations are carried out after drainage and pressure relief in the tunnel.

However, direct measurement poses a significant challenge. Therefore, simpler alternatives such as Schmidt hammer rebound number (SRn), P-wave velocity (Vp), and point load index (<em>Is</em>) are frequently used to estimate UCS indirectly. In this study, we compiled a comprehensive dataset of 1168 samples that included SRn, Vp, Is, and UCS values. The dataset was refined using an isolation forest algorithm, which identified and removed 280 outliers, leaving a dataset of 888 samples for analysis. We developed and assessed an automated machine learning (AutoML) model for predicting UCS, introducing a novel approach to tackle this prediction challenge. Additionally, we compared models enhanced by Bayesian optimization, including multi-layer perceptron (MLP), support vector machine (SVM), Gaussian process regression (GPR), and K-nearest neighbor (KNN). Among these, the AutoML model demonstrated superior performance in UCS prediction, offering a rapid and efficient method for estimating UCS in engineering applications and enabling intelligent classification of rock masses. The study also evaluated the sensitivity and contribution of SRn, Vp, and Is in UCS estimation by various techniques, including permutation feature importance (PFI), SHapley Additive exPlanations (SHAP), and local interpretable model-agnostic explanations (LIME).

This not only causes damage to surface buildings but also may have irreversible impacts on the aquifer. Taking 1208# working face of Hongyang No. 3 Coal Mine as a case in study, this paper uses the Small Baseline Subset Interferometric Synthetic Aperture Radar (SBAS-InSAR) technology to systematically monitor and analyze the surface subsidence characteristics of the multi-mining area (MMA) and the single-mining area (SMA) changing over time, with a focus on discussing the subsidence laws of the MMA. The comparative analysis results show that: (1) There is an obvious hysteresis in surface subsidence, the position of the subsidence center basically corresponds to that of the working face, but the influence range of subsidence exceeds the boundary of the working face, besides, significant surface subsidence occurred 36 days after mining the No. 1208 working face, and the change in the structure of the overlying strata was transmitted to the surface; (2) Compared with the single-mining area (SMA), the maximum subsidence rate (MSR) and the maximum subsidence value (MSV) in the multi-mining area (MMA) are higher, and both the subsidence center and its influence range are significantly expanded; and (3) After the mining of the working face stops, the subsidence rate slows down, but the subsidence increment in the MMA area is still higher than that in the SMA.

A multi-index fuzzy comprehensive evaluation model was established based on the acoustic emission (AE) characteristic parameters to quantitatively evaluate the possibility of rock failure. In the fuzzy comprehensive evaluation model, the exponential distribution function in reliability theory was introduced, and the membership function was constructed by Gaussian distribution.

The research explores how changes in size affect both the temporal and spatial distribution of tunnel temperatures and freeze-thaw depths. The findings reveal that traffic wind significantly influences tunnel temperature fields, with larger amplitudes observed when accounting for traffic wind compared to no-traffic wind conditions. Additionally, peak temperature of surrounding rock decreases logarithmically with increasing tunnel diameter and depth, while freeze-thaw depth decreases logarithmically with increased section size. Furthermore, the peak temperature of surrounding rock and the freeze-thaw depth are inversely proportional to the tunnel length. Based on these observations regarding section size and length's impact on temperature fields, a mathematical relationship between freeze-thaw depth within surrounding rock and tunnel dimensions is established to elucidate the size effect on temperature fields.
