摘　　要：为解决复杂山区地质选线中的有效性问题,提出一套综合地质勘察方法,以四川省泸定至石棉高速公路为例,通过采用1∶10000大范围的工程地质专项调绘、沿线断裂构造专项研究、多光谱遥感地质灾害解译研判、INSAR专项遥感勘察监测研究、水文地质专项调查、泥石流专项调查等专题研究,并结合地质钻探、工程物探等综合地质勘察方法,在充分把握场区地质体分布规律与发展特征的基础上,本着地质选线的原则,并结合结构物特征、工程规模及安全风险等综合因素进行多方案比选,选出最优方案,供复杂山区地质选线参考。To solve the problem of effectiveness in geological route selection in complex mountainous areas,a set of comprehensive geological survey methods is put forward.Taking Luding-Shimian Expressway in Sichuan Province as an example,special surveys of engineering geology with a scale of 1∶10000,special research on fault structures along the route,interpretation and judgment of multi-spectral remote sensing geological disasters,special remote sensing survey and monitoring research of INSAR,special investigation of hydrogeology and special investigation of debris flow are adopted.Combined with comprehensive geological survey methods such as geological drilling and engineering geophysical prospecting,on the basis of fully grasping the distribution law and development characteristics of geological bodies in the site,and in line with the principle of geological route selection,and combining with comprehensive factors such as structure characteristics,project scale and safety risks,the best scheme is selected,which can be used as a reference for geological route selection in complex mountainous areas.
