广东省东江—深圳供水改造工程凤岗隧洞施工技术

Fenggang Tunnel construction technology for Dongjiang-Shenzheng Water Supply Modification Engineering in Guangdong Province

介绍了广东省东江—深圳供水改造工程中凤岗隧洞标段的施工情况,着重介绍了超前支护、隧洞掘进、施工测量以及变形监测等技术措施的应用情况。其中的一些经验和做法对在地质条件较差的情况下进行地下工程施工具有一定的借鉴意义。

The paper introduces the Fenggang Tunnel construction for Dongjiang-Shenzheng Water Supply Modification Engineering, especially in advance support, tunnel excavation, construction survey and deformation monitoring. Some experience and measures may be used for reference to construction at the location where geologic conditions are not good.
