综合物探法在眉山艾普照能工程勘察中的应用
|
摘要
物探方法由于高效、无损等优点,广泛应用于工程地基勘察中。在实际工作中,单一的物探方法虽各有所长,但趋于片面,难以确定异常的物质成因,从而达不到预期的应用效果。该文以高密度电法和地震反射波法在某工程勘察中的综合应用为例,介绍了这两种方法的基本原理、方法以及获得的成果,并依据钻探资料对这两种方法的结果做了进一步对比和修正,最终推断覆盖层、基岩等地下地质结构情况,综合评价工区的地层分布情况,为施工建设提供了可靠的依据。
Because of advantages of high efficiency and no damage etc.,the geophysical prospecting method has been widely applied in engineering foundation investigation.In practical work,a single geophysical prospecting method has its own advantage,but it is difficult to determine the abnormal material genesis,so it can't achieve the expected effect.In this paper,taking a comprehensive example of high density resistivity method and seismic reflection wave method applied in certain engineering survey,the basic principle,methods and the obtained results are introduced,and made further comparison and correction for two methods according to drilling data.Finally we inference underground geological structure of overburden layers and bedrock,evaluate the formation distribution in project area comprehensively,which provides the reliable basis for engineering construction.
