摘要

对上海复兴东路越江公路隧道——近间距双线盾构隧道同向施工时相互影响的现场监测进行了研究。首先简要介绍了工程背景及其概况

然后介绍了为研究近间距盾构隧道相互影响而布设的监测项目

包括深层土体水平位移、地表沉降以及深层土体沉降、北线隧道三维位移、圆周变形、接缝宽度、北线隧道所受水土压力、北线隧道衬砌内力和土体中的超孔隙水压力。对监测数据进行了详细研究

得到了后建隧道推进时对地面沉降、深层土体位移变化、超孔隙水压力产生和消散、先建隧道衬砌位移、变形、内力的影响规律。从现场监测的分析结果来看

后进隧道对周围土体和先建隧道的影响是十分明显的。研究结果可以为大直径近间距双线推进的越江盾构隧道的设计和施工提供更加科学的指导。

Abstract

It is important to evaluate the interaction between the twin large tunnels in close space to facilitate its economical and safe design and construction.The paper mainly involves the field monitoring on interaction between the twin large diameter slurry shield tunnels in close space—East Fuxing Road Tunnels across the Huangpu River.Firstly

it introduces the origin and background of the subject

the engineering situation.Then

it introduces the field monitoring including horizontal displacement of deep soil

settlements of ground surface and deep soil

three-dimensional displacements and deformation of the north tunnel

the water-soil load acting on the north tunnel

internal force of the north tunnel

the excess pore water pressure in soil.Through analyzing the field monitoring data

the rule that the constructing shield affects the settlement of ground surface

the displacement of deep soil

the excess pore water pressure

the displacement and deformation and internal force of the existing tunnel

are obtained.Obviously

the interaction is very more than estimated.And the actual internal force could be much than the adopted for the design.
