地质调绘在山区公路路线方案设计中的重要性

Importance of Geological Mapping in Scheme Design of Highway Geometry in Mountainous Areas

随着我国工程建设的不断发展,我国高速公路建设已经全面进入山区化。山区高速公路建设具有地形地貌复杂、区域构造发育、地质灾害多发的特点,因此工程地质勘察已逐步成为建设过程中的重中之重。工程地质调绘作为一种勘察手段,在前期选线中发挥着举足轻重的作用,对后期工程建设往往也能起到事半功倍的作用。通过实际案列,简述了山区高速公路前期选线中工程地质调绘的重要作用。

With the increasing development of China’s infrastructure construction, China’s expressway construction has fully entered the mountainous area. The construction of expressways in mountainous areas is featured with complex topography, developed regional structure and frequent geological disasters. Therefore, geotechnical investigation has gradually become the top priority in the construction process. As one of survey tools, engineering geological survey and mapping play an important role in early route selection and can often get double results with half effort for later construction phase. Through the actual case, in this paper the importance of engineering geological mapping in the early route selection of mountainous expressway is briefly described.
