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。
With the rapid development of transportation, it plays a crucial role as a bridge connecting the roads. However, due to historical and financial reasons, most of the bridges built in the 1960s, 1970s and even the 1950s in our country are still in operation. Due to their low design load and low bridge width, these bridges have become Potential hidden danger. In this paper, a comprehensive test including appearance, crack, strength, strain and deflection of a reinforced concrete hollow slab bridge was carried out, and the test results were used to evaluate the serviceability of the bridge comprehensively. The assessment results show that the bridge lateral force transmission Poor, lack of stiffness, should be timely reinforcement of the bridge.
