摘要
为了使桥梁静载试验结果更加准确可靠,探索采用有限元软件midas Civil对3×20 m曲线梁桥静载试验进行仿真模拟,并在此基础上对静载试验方案进行了优化。试验结果表明,有限元模拟桥梁静载试验方法准确可靠,桥梁刚度和承载能力满足设计要求,并通过对试验结果与模拟结果及规范值的比较分析,对桥梁结构做出总体评价。
In order to make the bridge static load test result more accurate and reliable, we simulated the static loading test of3 × 20 m curve beam bridge by exploring finite element method, and optimized the test scheme on this basis. The results show that, the method of simulating the bridge static load test by finite element is accurate and reliable, the structural rigidity and bearing capacity satisfy the design requirements. A general evaluation of bridge structure is made by the comparative analysis on the test results, the simulation results and the standard value.
