摘要
结合工程实例,介绍了基坑支护优化设计思路与方法.基坑支护分段采用了不同的形式,通过灵活运用旋喷桩止水帷幕、悬臂桩和喷锚等施工技术,既保证了工程安全,又大幅度地降低了支护造价.
Combined with the case of Qingdao Liuting International Airport（QLIA） construction, this paper introduces the supporting design method of foundation pit. Different types of support are adopted in different sections of the foundation pit, not only assures the project safety, but also decreases the supporting cost in a large scale by utilizing the construction technology of churning piles cofferdam, cantilever piles and spray anchoring, etc.
