地球物理勘探方法在工程勘察中的综合应用

简要阐述了目前在铁路、公路等工程勘察中广泛应用的浅层折射地震层析及高密度电法两种物探勘探手段的工作方法原理。通过在新建兰新铁路勘察项目中的综合应用实例,说明只要在工作中选择合适的观测参数和解释方法,结合钻孔等相关地质资料,对相对较浅的地质构造、水文地质、小断裂构造及不良地质现象的分布、形态及规模等均可进行较为详细勘察。加上两种方法成果相互验证,不仅提高了勘察精度及可靠性,同时也为铁路、公路等建设施工提供了可靠依据。

Comprehensive Application of Integrated Geophysical Method in Engineering Investigation

This paper briefly describes the principle of the shallow refraction seismic tomography method and the high-density electrical method which are widely used in railway,highway,and engineering investigation.through the new project of Lan-Xin Railway,the comprehensive survey application example shows that,as long as the observation parameters and interpretation method are suitably selected,we can perform the detailed investigation for those relatively shallow geologic structures,the hydrology geology,the small...
