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。
Harbin Wang (Gang) Wan (Le) Line Songhuajiang Bridge uses (60 + 9 × 96 +60) m rigid continuous girder bridge structure with novel structure, which is an important bridge across the Songhua Channel. According to the structural characteristics of static load test research, the test includes the stress test of concrete girder, rigid concrete pier concrete stress test, mid-span deflection test and beam end angle test. The test results show that the factors of stress, strain, deflection and rotation angle are all less than 1, and the ratio of static and dynamic load to span meets the requirements of the code. The structure is under elastic force to meet the requirements of safe operation.
