拱桥立柱盖梁裂缝分析

Crack analysis of arch bridge column cover beam

以某拱桥立柱盖梁为例,针对其裂缝发展进行参数分析,以期找到盖梁裂缝产生的原因,为后期桥梁的养护和运营提供参考。分析发现,裂缝的产生虽然是多因素作用的结果,但温度作用较其他因素来说影响较大,检测时发现盖梁普遍存在水蚀、垃圾堆积现象,后期养护应及时处治。

Taking an arch bridge column cap beam as an example,this paper analyzes the development of cracks in the cap beam,hoping to find out the causes of cracks in the cap beam and provide a reference for the later maintenance and operation of the bridge.It is found that although the cracks are the result of multiple factors,the effect of temperature is greater than others.During the detection,it is found that there are water erosion and garbage accumulation in the cap beam,so that the maintenance shall be carried out in time.
