蒙华铁路黄土滑坡风险评价研究
Research on Risk Evaluation of Loess Landslide along Mengxi-Huazhong Railway
摘要
Abstract
In order to reduce the harm of the unfavorable geological conditions, like landslide, in the course of railway construction and operation, it's necessary to evaluate the hazard of landslide in the study area, where railway route will be selected. The risk evaluation of the loess landslide at loess plateau area of Mengxi-Huazhong is conducted based on remote sensing and GIS technology. 18 landslide influencing factors are identified and quantified by analyzing the internal relation between landslide factors and environment using GIS technology. Weight Overlay Model for risk evaluation is built based on the results of remote sensing interpretation of landslide and source data of influencing factors. This model realizes landslide hazard zonation and classification by a new factor weight calculation method, which is objective and reliable based the mathematical relationship established between the variation of landslide and the variation of research area. Based on the risk evaluation results of loess landslide, the designed railway routes are compared and the optimum scheme is proposed. This research results can be applied to the design of railway route selection, disaster prevention and reduction.关键词
