摘要
岩溶地区深基坑开挖常诱发较多的环境工程地质问题。基坑排水形成地下水降落漏斗,诱发岩溶地面塌陷;开挖导致基坑壁滑塌;造成周围建(构)筑物破坏或局部拉裂。本文分析了工程地质条件、水文地质条件、基坑支护体和周边建筑等对深基坑开挖的影响。提出了深基坑开挖中应注意的问题以及防治措施。
The excavations of the foundation pits in the karst regions frequently generate the geological issues in environmental engineering. Drainage of the foundation pit formed the landing funnel of underground water which induce rocky surface collapse; the walls slump of the foundation pit are resulted in the excavation; meanwhile the breakage or partially rip formed of the constructions in the vicinity. In this paper, the influence on the foundation pits in excavation involved engineering geology, hydrologic geology, shields of foundation pits and surrounding buildings are investigated. Essentials and control measures are put forward in unearthing the foundation pits.
