海相淤泥质土基坑开挖变形特征监测分析

Analysis of Monitoring Deformation Characteristics of Pit Excavation in Marine Silt Soft Soil

在基坑开挖过程中,由于海相淤泥质土具有压缩性大、渗透系数低的特点,容易引起围护结构的较大变形,使得工程的安全性降低.以连云港地区某基坑为例,详细介绍基坑的监测方案.通过对基坑监测结果的分析,讨论海相淤泥质土中基坑开挖的变形特征.

In the course of pit excavation,the enclosure structure is likely to be deformed,thus making the engineering project less safe,because marine silt soft soil is highly compressible and low in permeability.Taking a pit in Lianyungang City for example,this paper expounds the monitoring of this pit.The deformation characteristics of pit excavation of marine silt soft soil are discussed by analyzing the monitoring results of this pit.
