Taken the construction of the shaUow-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 construction and under different operation conditions are analyzed and calculated with the 3D finite element program ADINA, and then the calculation results of the intemal 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.
