| Abstract: | Some cast-in-place box girders of Haideng main line birucation interchange on Xiamen-Zhangzhou expressway and Zhangzhougang interchange viaduct are located in the deep soft soil foundation. The combination of PTC pile foundation, concrete ground beam and Bailey beam bracket successfully overcome the difficulties of low bearing capacity of the soft soil foundation and uneven settlement and helps to complete the upper structure construction. The construction scheme, safety and quality control points and effect evaluation and so on can be used for references in the similar projects. |
