考虑拱上建筑受力的实腹式石拱桥实测分析

目前我国有大量石拱桥进入安全评估期,然而通过荷载试验评定其使用性能时,存在设计计算模型与实桥受力状况不一致的问题,检测过程中该如何考虑、以及如何考虑拱上建筑参与受力是目前桥梁检测评价中遇到的难点问题。通过一座实腹式石拱桥的荷载试验测试,分析了实腹式石拱桥的受力特点及建模计算时应考虑的问题,并通过实测数据的分析比较,校核计算模型的合理性,为同类型拱桥的检测评定提供参考。

The Measurement Analysis of Solid Stone Arch Bridge Considering Arch Construction Stress

Through a load test of a solid stone arch bridge, this paper analyzed the stress characteristics and the consideration should be given to the problem of modeling calculation of the solid stone arch bridge. Through the analysis and comparison of the measured data, it also checked the rationality of the calculation model, which provided the reference for the detection and evaluation of the same type of arch bridge.
