摘要
结合泸州长江铁路大桥水中墩基础的水文地质情况,介绍大桥深水基础施工常用的双壁钢围堰、吊箱围堰两种防水结构的方案比选,特别是3#墩在岩面高差达13.5m的情况下,采用外置钢插板的施工方案,可供同类桥梁参考。
Combining the hydrological and the geologic conditions of the pier foundation in deep water of the Luzhou Changjiang River Railway Bridge, this paper presents the scheme comparison and selection of the double-wall steel boxed cofferdam and integral steel boxed cofferdam. No.3 pier 13.5m height difference between rock tops adopts external steel spiel. This can give reference to the similar construction of bridge.
