严重偏压浅埋隧道进洞施工技术

The graveness bias-voltage shallow-buried tunnel shallow-buried entrance construction technology

从地表处理、施作偏压挡墙、洞身开挖、初期支护、二次衬砌和防排水处理等方面详细介绍了广州—珠海城际轨道交通工程凤凰山浅埋偏压隧道进洞施工技术,指出施工中应注重环境保护,同时为偏压隧道提供了成功的进洞经验。

From the surface management, constructing bias-voltage retaining wall, the excavation of tunnel, the support in early stage, the second liner and the management of water proof and drainage, it specifically introduces the bias-voltage shallow-bui＇ied bias-voltage tunnel shallow-buffed entrance construction technology of Fenghuang mountain of the traffic projects from Guangzhou to Zhuhai, and gives the successful entrance experience to bias-voltage tunnel.
