摘　　要：随着交通事业的高速发展,作为连接道路的桥梁起着至关重要的作用。但由于历史和资金等因素,我国大部分20世纪60、70年代甚至50年代修建的桥梁仍在营运使用,且因其设计荷载标准偏低、桥梁宽度偏小,导致这些桥梁已成为交通运输中潜在的隐患。本文对某钢筋混凝土空心板桥进行了包括外观、裂缝、强度及应变、挠度等在内的综合检测,并利用检测结果对该桥的使用性能进行综合评估,评估结果表明,该桥横向传力不佳,刚度不足,应及时进行桥梁加固。The bridge as linking road has taken an extremely important effect along with the highway traffic developing at top speed.But most of the bridges built in the sixties or seventies even in the fifties last century are still being used now because of history and fund.And there exist some factors which are the lower designed load standard and narrower width of the bridges.All these factors make the bridges exist some hidden danger.In this paper,the comprehensive test which includes the tests on appearance,crack,strength,stress and deflection is done on a RC hollow slab bridge.Then an evaluation about service performance of the bridge is done by the test results.The results showed that transverse force transmission of the bridge is not good and its stiffness is insufficient.The bridge should be reinforced timely.
