软基某深基坑监测分析与研究

Analysis and Research on Monitoring of a Deep Foundation Pit on Soft Foundation

软土地基深基坑工程桩、围护结构、防渗体系、土方开挖及拆撑施工过程中会引起支护结构及周边环境的变形与应力变化,通过对基坑支护结构及周边环境进行监测,获取准确可靠的变形与应力变化信息,施工过程中将各测项的变形与应力变化信息进行综合分析,判断基坑开挖的安全风险,实时调整施工工艺,为基坑开挖的安全进行保障护航。本文对软基某深基坑监测成果进行了综合分析,研究了变形及应力变化的成因,旨在为类似地质条件的深基坑安全施工提供参考依据。

The deformation and stress changes of the supporting structure and surrounding environment can be caused during the construction process of piles,retaining structures,anti-seepage systems,earthwork excavation,and dismantling of supports in deep foundation pit engineering on soft soil foundation.By monitoring the supporting structure and surrounding environment of the foundation pit,accurate and reliable deformation and stress change information can be obtained.During the construction process,the deformation and stress change information of each measurement item will be comprehensively analyzed to determine the safety risks of foundation pit excavation,Real time adjustment of construction technology to ensure the safety of foundation pit excavation.This article comprehensively analyzes the monitoring results of a deep foundation pit on a soft foundation,studies the causes of deformation and stress changes,and aims to provide reference for the safe construction of deep foundation pits under similar geological conditions.
