纵波横波联合地震勘探在城市地质调查中的应用
|
摘要
在城市地质调查中,物探方法的选择要结合地质背景,充分考虑地球物理前提和地质勘查目的,注重方法的可行性、有效性和适宜性。本文结合杭州市城市地质调查中浅层地震勘探,在第四系厚覆盖区,针对查明基岩埋深、确定松散沉积层的分层。在基岩埋深不同,松散沉积结构不同时选择有效的勘查手段、数据采集时的震源及参数选择等方面进行了探讨。
The selection of geophysical exploration method must to be considered feasibility,validity and expediency of the method and geological background,the precondition of geophysical as well as exploration purpose in the geological survey.We're referring to integrate with the shallow layer of earthquake in Hangzhou urban geological survey in this paper.During area of thick coverage of the Quaternary,this paper make scientific researches on finding out the buried depth in bedrock,ensuring the lamination for loosening sediment pile,and expresses the selection valid artifice to exploration in this respect.When the buried depth in bedrock differs from frame in loosening sediment pile,we sould use different investigation methods.
