摘　　要：以实际项目的双体承压舟浮桥结构设计为背景,对不同横舱壁位置、底封板数量和连接桥跨度下的承压舟结构受力进行了对比分析。建议保留原设计方案的横舱壁设计,底封板数量应由4块增加至8块,可适当增加连接桥跨度以提升汛期泄流和河中漂浮物通过的能力。Based on the structural design of practical project catamaran pressure vessel floating bridge,this paper makes a comparative analysis on the stress of pressure vessel structure under different transverse bulkhead positions,the number of bottom sealing plates and the span of connecting bridge.It is suggested to retain the design of transverse bulkhead in the original design scheme,increase the number of bottom sealing plates from four to eight,and appropriately increase the span of connecting bridge to improve the ability of discharge and floating objects in the river in flood season.

关 键 词：双体承压舟浮桥 横舱壁 底封板 连接桥跨度 结构优化
