桥梁荷载试验法是对桥梁结构工作状态进行直接测试的一种检定手段,通过动、静荷载试验测试出桥梁结构的各种动、静载响应,评定桥梁实际承载能力和受力性能,是评价桥梁性能最可靠的一种方法。本文以固本溪大桥为例,通过对该桥的现场静动载试验与桥梁有限元模型仿真分析,对桥梁整体受力性能和承载能力做出了评价,为大跨度预应力混凝土连续刚构桥桥梁的性能评估提供参考。
Bridge load test method is a test method for direct test of the working status of bridge structure. Through dynamic and static load tests, various dynamic and static load responses of bridge structures are tested, and the actual bearing capacity and mechanical performance of bridges are evaluated. One of the most reliable methods of bridge performance. Taking Gubenxi Bridge as an example, this paper evaluates the overall mechanical performance and bearing capacity of the bridge through the on-the-spot static and dynamic tests and the finite element model analysis of the bridge. It provides a theoretical basis for the long-span prestressed concrete continuous rigid-frame bridge Provide a reference for the performance evaluation of bridges.
