混凝土宽箱梁桥荷载试验检测分析

Detection and Analysis on the Concrete Wide Box Beam Bridge Load Test

单箱多室箱梁桥整体结构为空间受力,在进行荷载试验检测时将其简化为平面受力结构模型误差较大。结合一工程实例研究单箱多室箱梁桥空间模型的建立与荷载试验的分析方法。

The overall structure of single - box muhi - cell box beam bridge is space stress, and simplifies it as plane stress structure model when conducting load test detection would cause big errors. By combining with an actual project, the establishment of single - box multi - cell box beam bridge and the analytical methods of load tests are studied.
