摘要
从应力路径对基坑工程变形的影响、深基坑开挖对坑内基桩受力特性的影响、基坑隆起和回弹作用三个方面研究了深基坑开挖对已有工程桩的直接影响,同时就基坑开挖对工程桩的间接影响做了讨论,分析了工程桩承载力变化以及桩身破坏原因。
The paper studies direct influence of deep foundation excavation upon existing engineering pile from three aspects, which includes the impact of stress route upon foundation engineering deformation, impact of deep foundation excavation upon foundation stress characteristics within the foundation pit, and foundation heave and rebound. It also discusses indirect influence of foundation excavation upon engineering pile, and fi- nally analyzes engineering pile bearing capacity change and pile damage causes.
