介绍了宁波北仑电厂二期工程地下连续墙支护结构的计算与监测。采用ALGOR有限元分析系统,对基坑开挖引起的应力场、位移场进行了分析计算。对墙体变形、钢筋应力、土压力及沉降进行了观测。通过计算值与实测结果的比较,分析了影响基坑变形的主要因素。
The calculation and monitoring of the diaphragm wall supporting structure of the second phase of Beilun Power Plant in Ningbo are introduced. Using ALGOR finite element analysis system, the stress field and displacement field caused by excavation are analyzed and calculated. The wall deformation, reinforcement stress, earth pressure and settlement were observed. By comparing the calculated value with the measured result, the main factors affecting the deformation of foundation pit are analyzed.
