摘要

On the basis of the features of structrual design for Xi’jiang river slurry shield tunnel,the technique of laying natural gas pipes in the tunnel is presented in this paper.Gas pipes can be fixed in working shaft and main tunnel with clips or other clamping apparatus,pipes outside tunnel can be fixed with flange in concrete pier on river bank.When designing the installation mode of gas pipes in shield tunnel,the very important issue is to analyze the strength of clamping apparatus subject to pipe deformation and displacement caused by gas pressures and temperature variation in addition to water buoyancy and anticorrision of gas pipes.The method of laying gas pipes in Xi’jiang river shield tunnel may provide effective guidance for the design and construction of gas and oil pipes in cross river shield tunnel under similar circumstances.
