摘要
以位于四川省广元市的绵广高速陵江大桥为例,对静载试验设计、有限元模型构建及试验过程及结果展开分析,结果表明,桥梁结构在试验过程中保持了较好的弹性工作状态,控制截面变形和平截面假定一致;结构竖向刚度及位移均满足实际荷载要求。静力荷载试验结果为该桥梁工作状态及承载力的评价提供了必要依据。
Taking the Lingjiang Bridge of Mianyang-Guangzhou Expressway located in Guangyuan City,Sichuan Province as an example,the static load test design,finite element model construction,test process and results are analyzed.The results show that the bridge structure maintains a good elastic working state during the test,and the control section deformation is consistent with the section assumption.The vertical stiffness and displacement of the structure meet the actual load requirements.The results of the static load test provide the necessary basis for the evaluation of the working state and bearing capacity of the bridge.
