文章以长沙磁浮工程榨山港栈桥设计施工为例，详细介绍了贝雷梁钢栈桥设计施工方法，从结构强度，刚度，稳定性方面说明了钢栈桥设计施工工程中的关键技术。由于工期紧，且地质条件复杂，采用修建临时道路或者绕道，都没有用贝雷梁架设速度快，节约工期，因此决定采用钢管桩上架设贝雷梁钢栈桥。文章目的在于介绍栈桥的设计、计算、施工方法，为今后类似工程提供参考。

This paper takes the trestle design construction in Zhashan harbor of Changsha magnetic levitation project as the example to introduce the design and construction method of steel trestle of bailey beam in detail and illustrate the key technology of design and construction of steel trestle from the strength, stiffness and stability of structure. Because of the short construction period and complex geological conditions, the speed of building temporary road or bypass is slower than using bailey beam and the construction period is long. So, the erection of bailey beam steel trestle on the steel pipe pile is used. The article aims to introduce the design, calculation and construction method of the trestle to provide references for the similar projects in the future.
