广州地铁9号线深基坑工程岩溶地质风险控制研究

Study on Karst Geologic Risks Control of Deep Foundation Excavation of the No.9 Line of Guangzhou Metro

以广州地铁9号线为例,分析了岩溶地区深基坑工程的风险,从勘察、设计和施工等几个方面介绍了岩溶地区深基坑工程的风险控制措施。对施工过程中发生的典型案例进行了分析。通过采取严密论证、详细勘察、科学设计、精细化管理等手段,全线的深基坑开挖风险得到了较好控制。

Based on the No.9 Line of Guangzhou Metro,this paper analyzed the risks of deep foundation excavation in karst area and introduced the measures of karst geologic risks control of deep foundation excavation from investigation,design and construction.The typical case in construction was analyzed.According to the measures as closely argument,detailed investigation,scientific design and delicacy management,the risk of foundation excavation was under control.
