利用熵权法开展普通公路地质环境隐患评价
Geological Environment Hidden Danger Evaluation of Ordinary Highway Using Entropy Weight Method
摘要
Abstract
In order to clarify the safety hidden danger level of ordinary highways,based on topography data,climate and meteorology data,referring to the relevant norms of geological environment risk disaster investigation and evaluation and the historical monitoring data of geological disasters,we selected six indexes of formation lithology,fault fold,DEM,rainfall,NDVI and historical data,and formed an index raster data with unified coordinate system and pixel size through the data processing of coordinate transformation,numerical transformation,spatial interpolation and grid transformation.We used the entropy weight method to evaluate the geological environment hidden dangers of ordinary highways.According to the evaluation results,we divided the safety hidden dangers of ordinary highways into five levels,such as not easy to occur,low easy to occur,medium easy to occur,high easy to occur and very easy to occur,and formulated different levels of safety monitoring frequency and safety protection measures,which was helpful for the safety and security of ordinary highway traffic.关键词
