灌注桩支护条件下的深基坑变形研究

Deep foundation pit deformation research under the condition of filling pile retaining

基于深基坑开挖过程中支护及其变形问题,采用PLAXIS软件对灌注桩的变形及受力、水平支撑的轴力、地表和基坑土中各点的变形及受力情况进行了数值模拟,并结合现场实测数据,得到基坑各个开挖过程及开挖完成后的变形情况,从而对深基坑的支护提出合理而有效的建议。

This paper made numerical simulation of deformation and load-carrying capability of filling pile,axial force of lateral bracing,deformation and load-carrying capability of surface and foundation with finite element software PLAXIS duing to shoring and deformation in the cource of excavation pit. According to measured values,then it made an result of foundation s deformation every time.So it can give an effective suggestion on deep foundation pit retaining.
