摘要

为检验(40+4×58+40)m上承式混凝土葵形拱桥的施工质量,评价桥梁结构实际承载能力,验证桥梁结构设计参数选取的合理性,对桥梁进行了静力荷载试验.通过优化荷载试验工况,测试静力荷载试验作用下结构控制截面的应力、变形,并与理论计算结果比较.结果表明,试验桥跨满足正常使用状态下的设计荷载等级使用要求.

Abstract

In order to verify the construction quality of a deck-type sunflower-shaped concrete arch bridge with a span combination of(40+4×58+40)m,evaluate the actual bearing capacity of the bridge structure,and verify the ra-tionality of the selection of bridge structure design parameters,static load test was conducted on the bridge.By optimi-zing the load test conditions,the stress and deformation of the structural control section under static load test were test-ed and analyzed.Comparing with the theoretical calculation results,it showed that the test bridge span met the design load level requirements under normal use.
