某基坑支护的施工设计及应急加固

Deep Excavation Support Design and Emergency Remediation

在市区复杂的场地进行基坑开挖,需要对不同区段所采用的与该区段地质条件相适应的基坑支护形式进行详细设计。以某实际工程为例,介绍了一个多种支护型式的基坑的设计过程及出现位移过大时的加固措施。

The detailed supporting design for different sections of a deep excavation is required if the subsurface conditions are complicated. This case history introduces the design aspects of a deep excavation project with multiple supporting schemes. The emergency supporting remediation measures for the excessive horizontal displacement during the construction are also dis- cussed.
