摘要

为查清某水库大坝坝基覆盖层厚度的变化规律,采用了高密度电法、浅层地震折射波法和瑞雷波法等三种物探技术,对其进行勘查,三种物探方法的定量解释结果基本一致;结合勘探成果验证,数据吻合,基本查清了覆盖层厚度的变化规律,证明了物探方法可以在该类勘察中发挥有效的作用。本次综合物探勘查取得了较好的应用效果,为工程设计提供了科学依据,也为综合物探方法在勘察中的应用提供了一个成功的实例,积累了一些应用经验。
In order to find out the change rule of covering layer thickness of a certain reservoir dam base,three methods,including high density electrical method,shallow layer seismic refraction prospecting and Rayleigh wave method,are used to investigate it.The quantitative interpretation of the three methods are almost the same.According to the validation results of the investigation,the change rule of the covering layer thickness was found out,which proves that Comprehensive geophysical prospecting method plays an important role in such investigation.Application effect was obtained from the Comprehensive geophysical prospecting,which provides technical support for engineering design.The most important is that this practice set a successful example to application of Comprehensive geophysical prospecting method to investigation as well as accumulating some practical experience.
