大跨度自锚式悬索桥静载试验及动力特性理论分析

对桌大跨度自锚式悬索桥进行了通车前荷载试验，试验内容包括四个工况，即主跨1／2截面、主跨1／4截面、塔梁结合处、边跨截面的应力和挠度试验；试验进行了平截面假定试验，了解了该桥在建成后的工作状态和安全承栽能力；最后，对大桥的动力特性进行空间建模和计算，得到大桥的动力特性，本研究对自锚式悬索桥的静力性能和动力特性获得了认识。

Theoretical Analysis on Static Load Test and Dynamic Property of Large- Span Self- Anchored Suspension Bridge

Load test before traffic opening is conducted for a large-span self-anchored suspension bridge.The test includes four working conditions,i.e.stress and flexure test of 1/2 cross section,1/4 cross section of main span,joint between bridgehead and beam and side span cross section;during the test,plane cross section hypothesis test is conducted,so that the working condition and safe bearing capacity of the bridge after construction is obtained.Finally,space modeling and calculation of the dynamic property of the bridge are performed and the dynamic properties of the bridge are obtained.This research provides some information about static force property and dynamic property about self-anchored suspension bridge.
