大跨度桥梁主墩施工栈桥及平台设计与施工

Design and construction of large-span bridge pile construction trestle bridge and platform

以某大桥的水中主墩及基础施工过程为例,介绍施工栈桥及施工平台的设计及施工工序,并对栈桥及平台的结构安全性作详细的检算,检算结果表明结构强度与稳定性均能够满足使用要求,实践证明该栈桥在整个施工过程中使用良好。

Taking the major water pier and foundation construction process of the bridge as an example, the paper introduces the design and con- struction procedure of large-span bridge pile construction trestle bridge, and calculates and checks the structural security of the trestle bridge and the platform. The calculation results show that structural intension and stability meet utilization demands. Practice proves that the usage of trestle bridge is great during the overall construction process.
