摘要

上海在区间隧道上方建造风井在国内尚属首例。随着人们绿色环保意识的增强

隧道通风井将会越来越多地修建在远离都市核心区的区间隧道的上方

因而研究风口基坑施工引起区间隧道位移的变化将会是岩土工程领域的又一崭新问题。本文结合上海人民路隧道风井风口基坑工程

针对是否降低承压水水位2种工况

采用M IDA S-GTS软件

对既有盾构隧道隆起进行数值模拟

从理论上量化在这2种工况下隧道的变形程度

探讨该方法的可行性

为最终选择何种工况施工提供了理论指导。实际的监测数据验证了本文方法的可行性

为今后的相关工程建设提供了一个成功范例。

Abstract

Nowadays

ventilation shaft construction in the running tunnel is the first case in China

As people’s awareness of environmental protection

away from the urban core area

more and more tunnel ventilation shafts would be built on the running tunnel.However

study on the tunnel displacement change due to ventilation shaft foundation construction is another new problem of geotechnical engineering area.Combined with ventilation shaft foundation of the Renmin Road tunnel

according to two working conditions

i.e.whether reducing pressure water or not

using MIDAS-GES software to analyze the running tunnel displacement

quantify the deformation degree of two conditions theoretically

discuss the feasibility of the method

and provide theoretical guidance to final choosing.The monitoring data also prove the feasibility of the method which provides an evidence for the same project construction.
