摘　　要：桥梁施工中,可用多用途浮箱拼组水上浮船浮运钢板梁,介绍了浮运船的构造,分别对空载、载重状况下的初稳性、稳性衡准数、避风状态下的稳性等进行了详细的分析计算,提出了设计施工中应注意的问题和建议。利用潮差顶落梁,操作简单、实用,供遇到类似问题的技术人员参考。In the construction of a certain bridge, a floating vessel made up of multi-purpose pontoons is used to float-move steel slab girders, the structure of which is presented in detail in the paper, with its stability analysed and calculated in detail when it is unloaded, loaded, and under the wind. The paper also offers proposals for and points for attention in design and construction. Taking advantage of the differences in tidal rise and fall, it is very easy and convenient to put the girders in place with the technique. It may serve as a useful reference for similar projects.
