平胜大桥自锚式悬索桥静载试验与评价

针对自锚式悬索桥静栽试验研究较少的现状，介绍主跨跨径为350m的独塔单跨混合梁自锚式悬索桥——平胜大桥主桥的概况、成桥静力特性、静载试验内容、测试方法、静载试验工况、荷载分级、测点布置、试验结果及有限元计算结果的对比，并作出了评价。有限元分析及静栽试验结果均表明：在成桥运营阶段，活载引起的平胜大桥自锚式悬索桥内力及线形变化与所受活载基本上呈线性关系；静载试验结果与理论计算值基本一致；残余变形、残余应变较小；在设计活载作用下，结构处于弹性受力状态，施工控制达到了较高的水平；同时也表明，静裁试验的理论分析模型很好地反映了实际桥梁的受力特性。

Static Loading Test and Assessment of Pingsheng Self-anchored Suspension Bridge

Confronted with the question that there is no literature concerned on static loading test and assessment of self-anchored suspension bridge,the general situation,static characteristics in completed state,contents of the test,measuring methods,operation modes,stage loading scheme,layout of measuring points,test result and assessment of the test of the main bridge of Pingsheng Bridge,which is a self-anchored suspension bridge with composite beam and a single span(350 m) and single tower,were introduced.The re...
