    IN-SITU TEST ON ACTIVE EARTH PRESSURE ZONE IN PILES AND ANCHORS SUPPORTING SYSTEM FOR DEEP FOUNDATION PIT

    • 摘要: 通过深大基坑桩锚支护体系主动区土压力现场试验,依据基坑工程时空效应理念,研究分析了在深大基坑开挖过程中桩锚支护体系的受力特性,得出了主动区土压力随开挖进程发展而变化的分布规律,对类似深大基坑支护体系设计时的土压力计算具有重要参考价值。

       

      Abstract: Field tests were carried out for examining active earth pressure zone near a deep and large foundation pit supported with piles and anchors.Based on the concept of spatial and temporal effect,the features of forces acting on the pile and anchor supporting system are studied and analyzed. The characteristics of the earth pressure in the active zone with respect to the pit excavation steps are obtained.The results can be a useful reference to the earth pressure calculation of similar deep and large foundation pits.
