摘　　要：成资大道综合管廊穿越成渝高速,项目旁边为既有资三路跨成渝高架桥,管廊走向与桥梁平行,正交于成渝高速,采用顶管施工技术。为减小高速公路路面不均匀沉降,在穿越高速公路段采取打入水平钢管桩,并通过锁扣连接成管幕。该方法在施工过程中有效控制了路面的不均匀沉降,减小了施工过程对路基的扰动,确保了地上建筑物安全。The integrated pipe gallery of Chengzhi avenue crosses the Chengdu-Chongqing expressway,next to the existing Zisan Road across the Chengdu-Chongqing viaduct,and the direction of the pipe gallery is parallel to the bridge and orthogonal to the Chengdu-Chongqing expressway,with pipe jacking construction technology.In order to reduce the uneven settlement of the highway road surface,horizontal steel pipe piles were driven into the section crossing the highway and connected to the pipe curtain by locking.The method effectively controls the uneven settlement of the road surface during construction,reducing the disturbance of the roadbed during construction and ensuring the safety of the buildings on the ground.
