摘要
百色水利枢纽导流隧洞地质条件复杂 ,不稳定～极不稳定的Ⅳ、Ⅴ类围岩占 5 4 % ,开挖洞径达 15m ,为了探讨在复杂的地质条件下大型地下洞室的成洞条件 ,设计中对洞轴线、隧洞的断面型式、洞型及支护型式进行了研究 ,其成果在工程施工中验证 :该设计方案合理 ,符合实际 。
The construction diversion tunnel geologic condition of BMPDP is complex, the non_stability surrounding rock of type Ⅳ and typeⅤ is 54%, and the cavity diameter is 15m. The authors probed into the forming condition of large sized underground cavity in complex geologic condition, studied the tunnel section type and support type. The design scheme was rational, the effect was well, and it was proved by engineering construction.
