摘　　要：南水北调中线穿黄隧洞(长度4.25km)工程地质条件复杂,隧洞外侧水土压力大,采用加装滚刀的泥水加压式盾构施工较为合适,施工技术难点多,难度大,对盾构的性能要求高,盾构必须在适应性、主要设备系统性能及技术服务等方面满足工程需要。The geological conditions of tunnel through Yellow River (total length 4.25km) in the middle line of water south to north project are very complicate and the water soil pressure is very high outside the tunnel. Slurry-water-pressurizing shield with additional rolling cutter is more suitable. But many technical problems will occur and great difficulties may be faced. The shield must achieve high performance requirements. The adaptability, system performance of main equipment and related technical service must meet the construction requirements.
