为了贯彻上海市中心城区架空线落地的要求，确保世博会期间能源供应需求，北京西路～华夏西路电力隧道得以修建。由于是连接浦东浦西，隧道线路不可避免要穿越浦江两岸。基于施工现场记录的施工参数，对顶管穿越浦江两岸防汛墙施工影响进行了分析。研究表明：顶管穿越重要建筑物时，应当尽量降低顶进速度，以减小土体扰动影响；同时合理控制顶管机头顶进姿态偏差，平稳穿越保护建筑物。根据现场监测的防汛墙位移，认为沉降曲线规律可以由最大隆起量、最大沉降量和沉降速率等三个沉降特征量加以诠释。

The Electrical Power Tunnel from West Beijing Road to West Huaxia Road is built to meet the demand of energy supply during the 2010 Shanghai World Expo. It crosses the Huangpu River and connects Pudong and Puxi. Based on the construction parameters in situ, this paper analyzed the effect of pipe jacking construction on the flood walls of both sides when pipe jacking crossed them. According to the research, while pipe jacking is crossing important buildings, pipe jacking speed should be decelerated as much as possible to decrease the soil disturbance. In the meantime, attitude deviation of pipe jacking head should be controlled within a reasonable range so that pipe jacking could cross the protected building smoothly. Besides, according to the displacement monitoring data of the flood walls, law of the settlement curve could be explained by three characteristic quantities of settlement, namely, the maximum upheaval, the maximum settlement and the settlement rate.
