岩溶土洞发育区地基塌陷的治理

Remeadiations of foundation collapse in the soil cavity area of karst

岩溶土洞是一种特殊的岩溶现象 ,具有埋藏浅、发育快、分布密、易引发地面塌陷的特点 ,对工程建设危害极大。本文以郴州师范学校教职工生活区地基塌陷治理工程为例 ,对岩溶土洞的分布规律、形成机理及地基塌陷原因进行了分析 ,并简要介绍了岩溶土洞的治理措施。

The soil cavity of karst is a special karst phenomenon.It lies in the shallow ground,developing quickly and distributing concentrately.It will do great harm to engineering.In this article,the distribution,the mechanism of forming and the reason of ground cave-in are discussed.The method of foundation treatment are also be introduced.
