一般桥梁结构动力性能数据分析研究

Research on Data Analysis on Dynamic Performance of Ordinary Bridge Structure

桥梁的长期监测、定期检测以及荷载试验已经纳入到日常的市政管养程序中,而荷载试验中,动载试验所测试的桥梁动力性能是评价桥梁稳定性和承载能力的重要指标之一。以常见的简支梁桥和连续梁桥为例,深入探讨桥梁动载试验测试项目的数据分析方法,为同类桥梁动载检测试验提供参考。

The long-term monitoring,periodic detection and load test of the bridge have been brought into the daily municipal administration management and maintenance procedure,whereas in the load test,the dynamic performance of the bridge tested by the dynamic load test is one of important indexes that evaluate the bridge stability and bearing capacity. Taking common simply supported girder bridges and continuous girder bridges as the example,the data analysis methods for the dynamic load test items of the bridge are further discussed,so as to provide reference for the dynamic load inspection and test of similar bridge.
