摘要
通过对某简支空心板桥进行静载试验和外观检测,测得控制截面在各种荷载工况作用下的挠度和应变,将其与理论计算值进行比较,以及与规范规定的裂缝宽度限值比较,可对该桥的使用性能进行综合评估。
By the static load test and appearance examination of the simply supported cored slab bridge,the deflection and strain of the key section have been measured in the proportional loading case.Comparing the measured data with the theoretic value and limited value of the crack width prescribed by the specifications,the service performance of this bridge can be evaluated synthetically.
