断层破碎带地质条件下明挖车站基底加固处理技术研究

Research on Reinforcement Treatment Technology of Base of Open Excavation Station under Geological Conditions of Fault Fracture Zone

地铁基坑开挖施工属于危大工程,在不同的地质条件下,开挖前可能会采取相应的措施来确保开挖施工安全。文中主要介绍了断层破碎带地质条件下,基坑开挖前,通过抽水试验确定是否采取基底注浆加固处理措施,为类似工程施工提供参考经验。

The excavation of subway foundation pit is a dangerous project.Corresponding measures may be taken before ensuring the safety of excavation construction under different geological conditions.This paper mainly introduces the geological conditions of the fault fracture zone,and uses the pumping test to determine whether to take the foundation grouting reinforcement treatment measures before the excavation,so as to provide reference experience for similar projects.
