隧道地表塌陷成因分析及治理对策研究

Study on formation cause of earth's surfacesubside of tunnel and countermeasures

论文以两个隧道的岩溶地表塌陷为例分析了岩溶地表塌陷的原因及其具体影响因素,为进一步的预测和治理岩溶地表塌陷提供了依据。介绍了隧道工程的地质特征、地貌特征以及防止突水引起地表塌陷的措施,涌泥引起地表塌陷的成因、定量探测方法和治理对策。本文认为对隧道施工中岩溶地表塌陷的影响应火岩溶发育程度的影响、地下水影响和覆盖层性质的影响等方面考虑。

It was introduced that tunnel engineer geology feature, and geography,and the measure of preventing from the land sink by sticking water out,and the reason of the land sink by spring mud up,and sound value method,and the tactics of avoiding the land sink.we believe that the infertion factor of the earths surface subside include that the rock dissoved development extent,underland water,and cover seam feature.
