摘要
川藏公路巴塘至拉萨段沿线边坡地质灾害较为严重.根据多年来采集的边坡灾害数据,利用地理信息系统(GIS)综合插值等多种方法分析了该段公路沿线典型边坡地质灾害的危险性.研究表明:低度、中度、高度危险区占总里程的78.9%,总长度1008 km,其中高度达到30.28%,而基本无危险区里程为270 km,占总里程的21.1%.通过野外复核,该分析结果较为合理可靠.
The slope geohazard along Batang-Lhasa section of Sichuan-Tibet Highway is serious.Based on the slope disaster data collected over the years,the risk of typical slope geohazard along the section is analyzed by using several interpolation methods of geographical information system(GIS).The results show that the low,medium and high risk zones account for 78.9%of the total distance,with the whole distance of 1008 km,among which the high risk zone reaches 30.28%,and the distance of basically no risk zone is 270 km,making up 21.1%.The analysis results are reasonable and reliable through field verification.
