地道塌陷灾害勘查技术与评价研究

地道塌陷是较为常见的一种地面塌陷灾害,它是先前开挖的人防工程年久失修之后塌陷至地表所致。为减小灾害损失,有效实施治理工程,需要开展详细的灾害勘查工作。本文以实际工作为例,在分析工作区内各类相关地质资料的基础上,通过现场调查,查明地道塌陷灾害的分布现状,然后利用综合地球物理勘探、钻探,钎探和槽探等方法,综合研究分析,准确查明地道的埋藏情况和分布位置。

Study on Exploration Technology and Evaluation of Tunnel Collapse Calamity

Tunnel collapse is one kind of common ground collapse calamity recently, it is due to the collapse of civil air-defense construction which was excavated many years ago and never had been repaired. In order to reduce calamity losses, and carry out the control project effectively, the detailed calamity exploration need to be done. The distribution of tunnel collapse calamities in the work area was identified based on the related geological data analysis and the ifeld investigation. And the authentic burial situation and the location of the tunnels were determinate by all kinds of geophysical methods, such as exploration, drilling, cone dynamic penetration and trenching.
