| Abstract: | Numerical analyses of the diversion tunnel excavating, support, operation and the final sealing period have been carried out by means of Elasto-plastic FEM. The displacement and stress distribution of surrounding rock and concrete lining are provided, and the design principle and engineering measurements for the diversion tunnel of the project are proposed based on the computational results. As a result, the difficult design problems of the diversion tunnel under high water-level condition have been solved. |
