摘要
目前的软土地区城市基坑支护结构的沉降监测方法分析不够全面,导致监测效果难以达到理想效果。以宁波市某工程为例,分析软土地区城市基坑支护结构,对H型钢基坑支护结构进行加固,利用PLAXIS有限元程序仿真进行模拟,分别对软土地区城市基坑支护结构的地表沉降程度、基坑墙顶沉降程度、地下管线变形程度、围护结构倾斜程度、立柱沉降程度进行模拟和分析,本研究对于同类工程开展有积极意义。
The analysis of the settlement monitoring method of the supporting structure of the urban foundation pit in the present soft soil area is not comprehensive,and the monitoring effect is difficult to achieve the ideal effect.Taking a project in Ningbo as an example,the support structure of the foundation pit of the soft soil area is analyzed,and the support structure of the foundation pit of the H-shaped steel is reinforced,and the simulation is carried out by using the PLAXIS finite element program to simulate the ground surface settlement degree and the settlement degree of the foundation pit wall in the soft soil area,The deformation degree of the underground pipeline,the degree of inclination of the enclosing structure and the degree of post settlement are simulated and analyzed,and the study is of positive significance to the similar projects.
