摘　　要：江苏南沿江城际铁路武进站综合交通枢纽工程以武进站为中心,是一个集铁路车站、地铁、公交车站、出租车及社会停车场、商业及办公用的综合客运枢纽,包含一座地下车站及其附属进出口连通道,一座地铁车站及其附属结构、风井等设施。在基坑南北两侧分别布置出土和材料运输车道。由于车道地面超载比原设计增加较多,可能影响基坑结构安全,为此开展了计算研究,分析了枢纽基坑一侧留土边坡稳定性和地铁车站基坑支护变形、受力及稳定性,并提出了相关安全建议。The Wujin station integrated transportation hub project of Jiangsu South Riverside intercity railway,centered on Wujin station,is an integrated passenger transport hub for railway stations,subways,bus stations,taxi and social parking lots,businesses and offices,including an underground station and its auxiliary access,a subway station and its auxiliary structures,air shafts and other facilities.The excavation and material transportation lanes are respectively arranged on the north and south sides of the foundation pit.Because the ground overload of the driveway is more than the original design,which may affect the structural safety of the foundation pit,the calculation and research are carried out,the stability of the retaining slope on one side of the foundation pit of the junction and the deformation,stress and stability of the foundation pit support of the subway station are analyzed,and the relevant safety suggestions are put forward.
