摘　　要：长大区域断裂等地质构造复杂、山区不稳定斜坡广泛分布以及岩溶发育,是复杂地质环境下山区高速铁路存在的主要工程地质问题。本文通过对西安至十堰高速铁路秦岭山区存在的主要工程地质问题进行地质条件综合分析,采用"大场景"三维立体遥感技术与野外调查相结合的地质调绘方法和现场钻探、各类物理勘探、综合测井、水文试验等结合后形成了新的综合勘察方法体系,详细查明了上述工程地质问题,提出了复杂地质环境下山区高速铁路空间地质综合选线原则。The main engineering geological problems of high-speed railway in mountainous areas under complex geological environment are complex geological structures,wide distribution of unstable slopes in mountainous areas and karst development.Based on the comprehensive analysis of the geological conditions of the main engineering geological problems existing in Qinling mountain area of Xi’an Shiyan high-speed railway,a new comprehensive survey method system has been formed by the combination of"big scene"three-dimensional remote sensing technology and field survey,field drilling,various physical exploration,comprehensive logging,hydrological test,etc This paper discusses the engineering geological problems and puts forward the principle of comprehensive spatial geological route selection for high-speed railway in mountainous areas under complex geological environment.
