摘要
该文以某在役钢管混凝土系杆拱桥为对象,通过介绍该桥静载试验的主要内容、测点的布设、对试验中各工况应变和挠度以及吊杆力的理论值与试验结果的对比分析,表明该桥的静力承载能力和工作性能良好,文中所述的方法和结论可供桥梁设计人员参考。
Taking a steel-pipe concrete bowstring arch bridge under service as an object,the article introduces the main contents of the static load test of this bridge and the arrangement of its measuring points,contrasts and analyzes various construction strains and deflections in the test as well as the theoretical value and test result of hanger rod force.It makes clear that the static bearing capacity and the working property of this bridge are good.The methods and conclusion described in the article can be referred for the bridge designers.
