关于旧桥静载试验的几点经验

Some Experience of Static Load Experiment for Old Bridge

基于近年来旧桥承载力测试的工作实际,介绍了相关经验,要注重桥况检查,并检查危害性裂缝和钢筋锈蚀程度;须正确布置应变片测点,充分认识测量数据的可靠性;要准确、巧妙地运用校验系数评价以及相对残余变形评价方法,可供类似工程参考。

Based on the working practice of old bridge carrying capacity test in recent years,the article introduces the relative experience to pay attention to the inspection of bridge status and to inspect the harmful cracks and steel bar rust level,correctly to arrange the test point of strain sheet,fully to understand reliability of testing data,accurately and skillfully to apply the checkout coefficient estimation method and the comparative residual deformation estimation method able to be referred for the similar projects.
