杨林塘大桥主桥支架钢管桩设计及现场承载力试验

Design of Main Bridge Bracket Steel Pipe Pile and Field Test of Bearing Capacity of Yanglintang Bridge

杨林塘大桥主桥跨航道段采用少支点支架施工,由于梁体跨度大、荷载大,支架下部采用钢管桩作为基础,本工程对钢管桩进行了承载力设计验算,并且在施工中对钢管桩进行了现场承载力试验,以确保梁体支架的稳定和整个工程的结构安全。

The construction of a few support brackets is used in the shipping section of the main bridge span of Yanglintang Bridge.The steel pipe pile is used as the foundation at the substructure of bracket because of the large beam span and the large load.The bearing capacity of the steel pipe pile is designed and checked in this project and the field test of bearing capacity of the steel pipe pile is carried out in the course of construction so as to ensure the stabilization of the beam bracket and the structural safety of the whole project.
