摘　　要：以某过江通道工作井为依托,建立数值模型,分析工作井端头加固、地连墙施工、基坑开挖及盾构施工对周边建(构)筑物的影响,确定设计方案的合理性,确保周边建(构)筑物变形在允许范围内。通过与监测数据进行对比分析,实际监测值变化与计算值基本保持一致,可为类似条件下合理的设计方案选择提供参考。Based on the working shaft of cross-river passage,a numerical model is established to analyze the influence of the end reinforcement of the working shaft,the construction of the diaphragm wall,the excavation of the foundation pit and the shield construction on the surrounding buildings(structures).The rationality of the design scheme is determined to keep the deformation of the surrounding buildings(structures)within the allowable extent.By comparing and analyzing with the monitoring data,the actual change of monitoring value is basically consistent with the calculated value,which can provide reference for the reasonable design scheme selection under similar conditions.
