| 英文摘要 | The safety of underground tunnels is a key problem of large substructure engineering during excavation and design. A new method to calculate the general safety factor of underground multi-tunnel is put forwarded based on the strength reduction theory. By the way of reducing rock material strength parameters (cohesion strength C and friction angle phi) step by step, the general safety of tunnels is got when the calculated result of excavation simulation shows that the equivalent plastic strain of rock wall becomes connection exactly. Engineering application indicates that the method of underground tunnels strength reduction is very useful for analysis quantitatively the general stability of tunnels and design of substructure. |
