摘要
对某预应力钢筋混凝土简支板桥进行静载试验和外观检测,测得该桥控制截面的挠度和应变。将其与理论计算值进行比较,结合裂缝检测数据,对该桥的使用性能做出评价。并通过原因分析,提出了相关加固修补建议。
A prestressed simply supported board bridge is tested and analyzed via static load, and its deflection and stress of control section are measured by means of on - site static loading test. The deflection and stress, as well as the crack detection are compared with theoretically calculated values as to evaluate the service performance of the bridge. Some advice is given according to the result of the test.
