| Abstract: | 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. |
