川藏公路地质灾害危险性评价
|
摘要
针对川藏公路沿线的地理环境选取了公路沿线灾害体、暴雨、年均降雨量、路基位置、岩性条件、地貌类型、地震烈度、年均温度、植被覆盖率、地质构造等10个地质灾害危险性评价指标,采用专家系统法赋值,通过层次分析方法确定指标权重,据此提出了川藏公路地质灾害危险性评价模型。在GIS技术支持下,建立了川藏公路地质灾害危险性评价数据库。把川藏公路地质灾害危险性评价模型与地质灾害危险性评价数据库相结合,将公路沿线的地质灾害危险性分为危险区、高易发区、中易发区和低易发区,分别占路线总长的8.57%、48.77%、39.05%、3.61%。研究成果为实施川藏公路地质灾害风险评估提供了科学依据。
On the basis of the geological environment along the Sichuan-Tibet Highway,ten evaluating indicators on the geological disaster fatalness around the highway,geological disasters,rainstorm,average annual rainfall,roadbed location,lithological condition,landform types,seismic intensity,average annual temperature,vegetation coverage and geological structure,are selected.Adopting expert system to double evaluation and using the analysis hierarchy process to ascertain the weight of index,accor-dingly,the evaluation model on the geological disaster fatalness along the Sichuan-Tibet Highway is put forward.On the support of GIS,the database of evaluation about the geological disaster fatalness along the Sichuan-Tibet Highway is proposed.And to combine that evaluation model and database,the geological disaster fatalness along the highway is divided into 4 parts: dangerous zone,high susceptible zone,middle susceptible zone and low susceptible zone,and in the total length of the highway,those 4 parts are 8.57%,48.77%,39.05% and 3.61% respectively.Ultimately,the results of the study provide some scientific evidence for the evaluation of the geological disaster fatalness along the Sichuan-Tibet Highway.
