某铁路π形梁桥的荷载试验研究

Study on the load tests of rail traffic π-shape girder

以某铁路桥为工程背景,通过结构计算、现场检测、荷载试验。评估受检π形梁的工作性能和承载能力。结果表明,受检π形梁的承载能力能够满足设计荷载等级的要求。工程为π形梁的后期养护及维修提供了基础依据,对同类型铁路桥梁的检测及其承载能力评价有一定的参考价值。

Taking a π - Shape girder as engineering background, the test process analysis is carried out through calculation, field inspection and load tests and the working performance and carrying ca- pacity of the π - Shape girder are assessed. The test results show that the experimental π - Shape girder＇s carrying capacity complies with the design requirement, which can be the basis for later ma- intenance and can be referred to by the similar engineering.
