Analysis on the Static Load Test of a Prestressed Hollow Slab Simply Supported Girder Bridge in Guangdong after Reinforcement

本文介绍了广东某简支梁桥加固后的静载试验,借助桥梁专用有限元计算分析软件仿真模型,对桥梁在试验荷载下结构实测挠度和应变与理论值进行比较分析,判断该桥梁结构加固后是否满足设计荷载要求,对桥梁后期运营及养护提供合理建议。

In this paper, the static load test of a simply supported girder bridge in Guangdong was introduced. With the help of FEM (Finite Element Method) software, which is especially applied for the bridge, the simulated model of the bridge is built. By comparing the test result including the measured deflection and strain with the theory value, we can draw a conclusion whether the strengthened bridge structure meet the design requirements. It can provide reasonable suggestions on the bridges post-stage operation and maintenance.
