城市可溶岩区地面塌陷灾害勘查重难点问题分析

Discussion of the key issue of subsidence disaster exploration in city karst area

结合岩溶地面塌陷勘查经验,从资料收集与整理分析、地质测绘、物探、钻探、试验等方面,阐述了地质调查工作的重点,在普查深圳市的基础上,将岩溶发育区作为重点研究区域,采取多种手段查明了可溶岩的分布范围及其发育规律。

Relied on the experience of karst collapse exploration,a series of site investigation method for karast collapse problem was proposed,which includes collecting and collating the data,geological mapping,geophysical prospecting,drilling,tests. Based on the Shenzhen general survey for all the test data,this study play insight into how to find karst developing region and obtain its location and growing-developing regularity.
