成桥静动载试验及分析

对某大桥进行了成桥静力和动力荷载试验及分析,通过现场静动力荷载试验,测得其各种力学指标和性能指标,并与理论计算的结果及相应规范的要求进行比较,从而对桥梁的整体性能和结构安全做出评价,以确保桥梁的主体结构处于完好的技术状态和良好的使用状态,保证桥梁投入使用后的安全运营。在对现场测试结果及理论分析结果进行综合分析、比较的基础上,对其进行总体评价,保证该桥长期稳定运营。进行的试验及分析对同类桥型具有借鉴意义。

Static and Dynamic Loading Experiment and Analysis of Built Bridge

The article introduces the static and dynamic loading experiment and analysis of a built bridge. Through the field static and dynamic loading experiments, various mechanical indexes and performance indexes of the bridge are given. After the comparison with the results of the theoretical calculation and the requirements of the relative standards, the overall performance and the structural safety of the bridge are evaluated so as to ensure the main structure of the bridge placing at the intact technical status and the good use status and to guarantee the safe operation after put into use. On the basis comprehensively analyzing and comparing the field experimental test results and the theoretical analysis results, the overall evaluation of the bridge is carried out to guarantee it under the long-term stable operation. The experiment and the analysis are importantly referred for the same kinds of the bridges.
