滑坡堰塞湖危险性预测与铁路减灾策略
Risk Prediction of Landslide Dammed Lake and Railway Disaster Mitigation Strategies
摘要
Abstract
considered in the railway alignment design stage.In this paper,a set of procedures for assessing the risks of landslide blocking are established,and the theoretical formula of each step is proposed.On this basis,a three-dimensional landslide model is established by ANSYS finite element software and FLAC3D finite difference software with reference to Desha landslide on Sichuan-Tibet Railway.The purpose is to analyze the stability of the landslide.And then the empirical formula is used to predict the risks of river blocking in case of large earthquakes.Finally,the influence range of the dammed lake and countermeasures for disaster reduction in line engineering are put forward.This paper not only provides reference for the design of line and the layout of major projects,but also promotes hopefully the development of the technologies to reduce disasters to mountain railway through case study.关键词
