Probabilistic Analysis of Slope Using Finite Element Approach and Limit Equilibrium Approach around Amalpata Landslide of West Central, Nepal

引用

International Journal of Geosciences 2024年第5期15卷 416-432页

作者： mahendra Acharya Khomendra Bhandari Sandesh Dhakal Aasish Giri Prabin Kafle Central Department of Geology Tribhuvan University Kathmandu Nepal Department of Geology Tri-Chandra Multiple Campus Tribhuvan University Kathmandu Nepal Sri Revana Siddeshwara Institute of Technology Visvesvaraya Technological University Bengaluru India

The stability study of the ongoing and recurring Amalpata landslide in Baglung in Nepal’s Gandaki Province is presented in this research. The impacted slope is around 200 meters high, with two terraces that have different slope inclinations. The lower bench, located above the basement, consistently fails and sets others up for failure. The fluctuating water level of the slope, which travels down the slope masses, exacerbates the slide problem. The majority of these rocks are Amalpata landslide area experiences several structural disruptions. The area’s stability must be evaluated in order to prevent and control more harm from occurring to the nearby agricultural land and people living along the slope. The slopes’ failures increase the damages of house existing in nearby area and the erosion of the slope. Two modeling techniques the finite element approach and the limit equilibrium method were used to simulate the slope. The findings show that, in every case, the terrace above the basement is where the majority of the stress is concentrated, with a safety factor of near unity. Using probabilistic slope stability analysis, the failure probability was predicted to be between 98.90% and 100%.
