深基坑工程桩锚支护结构监测及分析

Monitoring and Analysis on Pile-anchor Supporting Structure of Deep Foundation Pit Engineering

结合河南省某深基坑工程实例,对深基坑桩锚支护结构开挖过程中各阶段的桩顶位移、桩身位移、桩的内力、土体分层沉降和周围建筑物沉降等进行分析,监测数据显示位移、内力、沉降变形的原因,验证基坑设计的科学性,避免基坑重大事故的发生。

Based on a project of deep foundation pit in Henan Province, the displacement of pile top, displacement of pile body, pile internal force, soil layer sedimentation and surrounding building sedimentation in various stages of pile-anchor supporting structure of deep foundation pit are analyzed, the reason of the displacement, the internal force and sedimentation deformation are inferred, the scientific design of foundation pit is verified, then the occurrence of major accidents of foundation pit will be avoided.
