本文结合杨家沟双曲拱桥加固后的静载试验,阐述了静载试验的方法,介绍了静载试验方案,并对试验结果进行了详细的分析。试验结果表明,该桥的刚度及承载能力能满足30t汽车的安全通行,桥跨结构在静力荷载下的变形特征和应变特征正常、整体受力性能基本满足公路Ⅱ级荷载的要求。该双曲拱桥的试验结论可为同类桥梁的静载试验提供参考。
Based on the static load test of Yangjiagou double-curved arch bridge, the static load test method is expounded, the static load test scheme is introduced, and the test results are analyzed in detail. The test results show that the stiffness and bearing capacity of the bridge can meet the safety requirements of 30t vehicles. The deformation and strain characteristics of the bridge span structure under normal load are normal, and the overall mechanical performance basically meets the requirements of Class Ⅱ load. The experimental conclusion of the double curved arch bridge can provide a reference for the static load test of similar bridges.
