摘　　要：以南水北调中线北京段浅埋暗挖输水隧洞施工为研究实例,使用三维有限元程序ADINA对隧洞衬砌在施工期及运行期不同工况下的受力状态进行了分析计算,得到了工程设计中比较关心的弯矩和轴力等内力计算结果,为工程设计提供参考。Taken the construction of the shallow-buried and underground-excavated water conveyance tunnel within Beijing Section of the Mid-route of the South-to-North Water Transfer project as an actual studying case, the stress status of the tunnel lining during the eonstruction and under different operation conditions are analyzed and calculated with the 3D finite element program ADINA, and then the calculation results of the internal forces such as bending moment, axial force, etc. concerned in the design of the project are obtained; which can be provided as the references for the design.
