宁波北仑电厂二期循环水泵房基坑支护与监测

Supporting and monitoring deep excavation of the phase II pump-station of circulation water of Beilun in Ningbo

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 retaining structures of diaphragm wall of the phrase II project of Beilun power station in Ningbo was calculated and monitored.By using ALGOR finite element analysis system,the stress field and displacement field of deep excavation were calculated.The paper gave some measured results including deformation of wall,steel stress,soil pressure and the settlement.Through comparison of calculation results and measured data,some main factors that affect the deformation of foundation pit were analyzed.
