摘要

重庆主城排水过江盾构隧道工程是国家重点环保工程之一，也是目前长江上最大的岩质盾构隧道。隧道采用泥水盾构机施工，其主体结构在施工期及运营期将承受0.6 MPa的高水压。研究高外水压力对隧道的影响具有重要意义，结合隧址区的地形地质及水文条件对施工期作用在盾构主体结构上的水压力进行了现场跟踪测试，探求施工期外水压力的分布规律，为盾构隧道的掘进控制提供参数，并为类似工程提供有益参考。

Abstract

Sub-river Shield Tunnel for Chongqing Urban Drainage Works is one of the state highlight environmental protection projects and the greatest shield tunnel in the Yangtze River. This sub-river tunnel is constructed with slurry shield machine. Because the main agent structure will bear 0.6 MPa high hydraulic pressure during both construction and operation period

it is significant to study the effects of high hydraulic pressure on shield tunnel. Based on topographic

geological and hydrological conditions in tunnel site

in-situ tracking test for hydraulic pressure on main agent structure of shield tunnel were carried out in construction period to acquire the distribution regularities of external water pressure and provide important parameters for tunnelling control. Thus

profitable references are provided for similar project construction.
