公路大跨度预应力连续梁桥初步设计

The preliminary design of highway long-span prestressed continuous girder bridge

以某公路跨河大桥为例,介绍了桥梁的结构尺寸设计要点,并对成桥结构的内力及次内力进行了分析,同时对施工阶段和营运阶段的应力进行了验算,证明了该跨河桥选用大跨度预应力连续梁桥的可行性。

Taking a highway across river bridge as an example, this paper introduced the structure size design key points of bridge, and analyzed the internal force and secondary internal forces of bridge structure,~ at the same time, checked the stress in construction phase and operation phase, verified the feasibility of this bridge selection of large span pre-stressed continuous beam bridge.
