| Abstract: | The refined three dimensional nonlinear finite element model of a large cross-river tunnel with more than two mil-lion nodes is established.In order to overcome computer runtime during solution of large tunnel,the parallel computing tech-nology with contact balance is adopted.The static stress field of the large cross-river tunnel is analyzed.The speedup of two kinds of partition scheme is also analyzed.The results can provide references for the design of large tunnel. |
