摘　　要：上海世博北京西路～华夏西路电力电缆隧道线路与轨道交通共有12处相交,其中10处为盾构法隧道穿越。对于如此大量的穿越轨道交通工程,电力隧道的设计中结合以往穿越轨道交通经验,针对盾构法隧道在运营过程中的止水效果不佳,造成后期沉降问题,进行了专项防水设计,以确保电力隧道及轨道交通隧道的正常运营。There are 12 intersections between power cable tunnel of Beifing West Road to Huaxia West Road and rail transit, ten of which are used by shield tunneling methods. Owing to the many shield tunnels, combined with the experience in rail transit through tunnel, special waterproofing measures are made to guarantee waterproof effects on shield tunnel during its using process, to avoid subsequent subsidence and to guarantee the power tunnel and rail transit tunnel run normally.

关 键 词：盾构隧道 隧道穿越 防水
