摘　　要：利用62式舟桥上部结构架设桥上桥，提出了具体的方案，进行了简化计算，并用空间有限元计算结果进行了验证。结果表明．该舟桥可用于解决特大荷载过桥时原桥结构承载力不足的问题。The detailed plan of constructing a bridge-on-bridge by using the upper structure of type 62 pontoon bridge is put forward. This plan is simplified calculated, and it is proved by the results of space finite element method. The results show that the bridge on-bridge can be used to bear special heavy loads.
