矮塔斜拉桥荷载试验方案分析

Analysis on Load Test Schemes for Short Tower Cable-stayed Bridge

对制定矮塔斜拉桥的荷载试验方案进行了分析,以大广高速公路黄龙带特大桥为依托,建立有限元模型,分析矮塔斜拉桥的结构受力特性,确定荷载工况与试验截面,计算试验荷载大小与位置,对加载工况进行合并,依据理论计算制定合理的静动载试验方案。可为同类型的桥梁荷载试验提供参考。

The load test scheme for a short tower cable-stayed bridge has been analyzed in this article. Being based on Huanglongdai Special Large Bridge of Daguang Express, a finite element model has been set up, the structure stressing features of the short tower cable-stayed bridge have been analyzed, the load case and test sec-tion have been determined, the load size and location have been calculated, the load case has been merged, rea-sonable static and dynamic load test schemes have been worked out on the basis of the theoretical calculation, which could provide references for the similar bridge load tests.
