大跨PC连续梁桥荷载试验研究

Research on Load Test of PC Continuous Beam Bridge with Large Span

桥梁荷载试验是对大跨度桥梁的承载能力和结构性能进行评价的有效手段。以某大跨PC连续梁桥为例,利用Midas软件建立有限元分析模型,依据相关规范规程对该桥进行荷载试验以及相应的分析,试验数据表明该桥主桥承载能力满足设计要求。

Bridge load test is an effective means to evaluate the bearing capacity and structural performance of long-span bridges.Taking a long-span PC continuous beam bridge as an example,the finite element analysis model is established through MIDAS,load test and the corresponding analysis are performed according to the related standards and rules of the bridge,and the experimental data shows that the bridge bearing capacity of the main spans satisfies the design requirements.
