摘要
哈尔滨王(岗)万(乐)线松花江特大桥采用(60+9×96+60)m刚构连续梁桥式,结构新颖,是跨越松花江航道的重要桥梁。针对结构特点开展静载试验研究,试验内容包括主梁混凝土应力测试、刚构墩混凝土应力测试、跨中挠度测试和梁端转角测试。测试结果表明,应力、应变、挠度和转角校验系数均<1,换算静活载挠跨比满足规范要求,结构处于弹性受力状态,满足安全运营的需要。
A novel structure of Songhua River bridge on Haerbin Wanggang-Wanle railway with a rigid frame continuous girder type,it is an important bridge across the Songhua river waterway. The static load test was carried out according to the structure characteristics. The test included the concrete stress test on beam and pier,deflection test on middle span,and the angle test on the conjection of beam and pier. The results show that the testing coefficient of stress,strain,deflection and angle was less than 1.0. The conversion static load deflection span ratio meets the requirements of the specification. The structure is still in the elastic state,and meets the need of safe operation.
