摘　　要：以珠三角水资源配置工程中的复合衬砌盾构输水隧洞为研究对象,在采用简化计算模型的基础上,利用ABAQUS有限元数值分析软件,分析不同外荷载工况下,不同埋岩深度及隧洞间距下管片衬砌环的应力和变形情况。由管片衬砌环最大径向变形及容许应力确定此时可承受的内水压力大小,并得到内水压力大小随埋岩深度和隧洞间距变化的影响规律,以供工程实践参考。Taking the composite lining shield tunnel in the Pearl River Delta Water Resources Allocation Project as the research object, based on the simplified calculation model, the finite element numerical analysis software （ABAQUS） is used to analyze the stress and deformation of segment lining in shield tunnel with different depth of buried rock and distance between the tunnels under different external load conditions. The internal water pressure can be determined according to the maximum radial deformation and allowable stress of the segment lining, and the influence law of the internal water pressure with different depth of the buried rock and distance between the tunnels is obtained, which provide references for engineering practice.
