浅层地震反射波法在长平高速公路塌陷勘察中的应用

Application of Shallow Meismic Reflection Wave Method in Survey of Collapse Area along Changping Freeway

该文论述了浅层地震反射波法的工作方法和数据处理技术,并介绍了长平高速公路坍塌勘察实例,经过对物探成果的分析解译,查明了路面下伏断层破碎带和塌陷区空间分布情况,并得到了钻探的验证。该次勘察为研究该路段下沉机制和塌陷趋势提供了可靠的地质资料。

This paper discusses the working method and data processing techniques of shallow seismic reflection wave method and introduces the collapse prospecting example of Changping freeway.Through the analysis and interpretation of geophysical prospecting results,the spatial distribution of the fault fracture zone and collapse area under the ground are explored,which are verified by drilling.This prospecing provides reliable geological data for studying the sinking mechanism and collapse trend of the area.
