Research on the Risk Assessment of Landslide in the North of Rangdu Field, Wanzhou District, Three Gorges Reservoir Area

摘要: 我国重庆市万州区地处三峡库区地带，多年来滑坡灾害发育显著，对乡镇等地发展速度与成效产生较大影响。本文以万州区瀼渡场北滑坡为研究对象开展单体滑坡风险评价研究，首先，基于野外实地调查，通过 GEO-Studio和DAN3D分别开展滑坡失稳概率分析及运动过程分析，得到滑坡危险性评价结果；然后，结合承灾体抗灾能力分析，开展易损性定量评价；最后，叠加滑坡灾害危险性、承灾体易损性及承灾体价值得到瀼渡场北滑坡风险评价结果。结果显示：瀼渡场北滑坡百年一遇的降雨强度下失稳破坏

Abstract: Located in the Three Gorges Reservoir area, Wanzhou District has witnessed significant development of landslide disasters over the years, which has had a substantial impact on the development speed and effectiveness of towns and other areas. This paper focuses on the risk assessment of individual landslides in the north of Rangdu field in Wanzhou District. Firstly, based on field investigations, GeoStudio and DAN3D were used to conduct landslide instability probability
