一种简支空心板桥施加横向预应力的设计方法

Design method of transverse prestress inflicted on the simply-supported hollow slab bridge

介绍了一种通过在简支空心板梁端和跨中增设预应力横隔梁来增强其横向连接的方法,以实例说明设计中横隔梁计算的内容,并从设计上对预应力混凝土简支空心板进行了改进和优化,以期指导今后装配式预应力混凝土桥梁设计。

This thesis introduces strengthening transverse connection method by setting crossbeam between simply-supported hollow slab girder end and the astride, illustrates crossbeam calculation content in the design with actual examples, and improves and optimizes the design of pressessed simply-supported hollow concrete slab bridge, so as to guide the design of assembled-type prestressed concrete bridge.
