摘　　要：结合西气东输二线长江盾构越江段工程,经过对复杂地质岩性及实际情况研究,系统分析了越江隧道泥水平衡盾构施工的适应性,这将直接决定和影响盾构隧道的施工成本、进度及安全风险。通过对开挖面稳定性控制、掘进参数调整及信息共享的研究,成功解决了在上软下硬地层中的掘进及盾构姿态难控制的难题。Combined with the construction of river-crossing segment of Yangtze River Tunnel in West-East Gas Transmission Project,the adaptability of slurry shield construction is analyzed through research on complex geological conditions and actual situation,which is crucial to the construction cost,schedule and safety.The problems of shield posture control and tunneling in complex soil are solved by controlling stability of excavation face,tunneling parameter adjustment and information sharing.
