梁式桥梁结构诊断性载荷试验分析研究

桥梁结构诊断性载荷试验可以实现对桥梁结构实际工作状态的了解。本文以实际工程为例,对在役桥梁进行诊断性载荷试验,确定了桥梁构件在给定荷载作用下的挠度和应变值,并依此对该桥进行加固。加固后的该桥的承载力性能和结构性能得到一定改善。

Analysis and research on diagnostic load test of beam bridge structure

The bridge structure diagnostic load test can realize the understanding of the actual working state of the bridge structure.Taking the actual project as an example,this paper carries out the diagnostic load test on the bridge in service,determines the deflection and strain value of the bridge members under the given load,and then strengthens the bridge according to the results.The bearing capacity and structural performance of the reinforced bridge are improved.
