【摘要】：随着基坑工程的积累,监测手段及监测数据的不断丰富,越来越多的实测数据表明水泥土加固、地下连续墙成槽、开挖卸荷等不同基坑施工阶段对周边环境均有一定程度的影响。为研究基坑施工过程中不同工况下周边土体变形的特性,选取上海软土地区较为典型的深基坑工程,对基坑工程周边环境的变形进行了全过程的监测,按照施工顺序,依次分析了不同工况下坑外地表隆沉的分布形式,总结了上海软土地区基坑工程的变形特征,并对基坑工程不同施工阶段的变形影响原因进行了分析。
[Abstract]:With the accumulation of foundation pit engineering and the continuous enrichment of monitoring means and monitoring data, more and more measured data show that cement-soil reinforcement, underground continuous wall into a slot. In order to study the deformation characteristics of surrounding soil in the process of foundation pit construction, the excavation unloading and other different excavation construction stages have a certain degree of influence on the surrounding environment. The typical deep foundation pit engineering in soft soil area of Shanghai is selected to monitor the deformation of the surrounding environment of the foundation pit project. According to the construction sequence, the distribution form of the pit surface uplift and subsidence in different working conditions is analyzed in turn. The deformation characteristics of foundation pit engineering in soft soil area of Shanghai are summarized, and the causes of deformation influence in different construction stages of foundation pit engineering are analyzed.
