连续刚构桥静载试验分析与研究

Static Load Test Analysis and Research on Continuous Rigid Frame Bridge

采用等效加载车辆法对连续刚构桥进行静载试验。结果表明:各工况下,所测得的结构各控制截面的主要测点位移、控制应变的结构校验系数均小于1.05,强度和竖向刚度均满足设计和使用要求;各工况下,全部荷载卸除后,残余变形与量测的总变形的比值小于20%,结构处于弹性工作状态。

Through using equivalent loading vehicles method to test continuous rigid frame bridge by static load,the results show that not only the testing coefficient of the main test point displacements and controlled strain of measured structural control section are both less than 1.05,but also strength and vertical stiffness both meet the design and use requirements.The ratio of residual deformation to measured total deformation is less than 20percent under different operation conditions,which shows that the structure is in elastic state.
