摘要
埋入式桥梁承台底被动区土体为软土地质,深基坑支护开挖方案对工程成本及施工效率有很大的影响。论文叙述软土地质承台深基坑预留核心土开挖施工关键技术,很好地解决了深基坑承台施工的工程成本和施工工效的问题。
The soil in the passive area at the bottom of the embedded bridge cap is soft, so the supporting and excavation scheme of deep foundation pit has great influence on the project cost and construction efficiency.This paper describes the key technology of reserving core soil for deep foundation pit excavation in soft soil, which solves the problems of engineering cost and construction efficiency in deep foundation pit construction.
