地铁换乘站周边建筑加固施工技术研究

Research on construction reinforcement technology around subway interchange station

地铁换乘站周边建筑较多,基坑开挖较深,极易影响周边建筑地基稳定性,造成不均匀沉降,以倪家桥站为例,对车站周边建筑注浆加固技术进行研究,确定了注浆加固所需材料和各项工艺参数,为类似工程提供参考。

There are many buildings around the subway transfer station,the excavation of the foundation pit is deep,which is easy to affect the stability of the surrounding building foundation,resulting in uneven settlement.Taking Nijiaqiao station as an example,this paper studies the grouting reinforcement technology of the surrounding buildings of the station,determines the materials and various process parameters required for grouting reinforcement,and provides reference for similar projects.
