伴随社会经济飞速发展的同时,我国部分现役桥梁由于交通量增长、本身设计缺陷、缺乏养护等原因产生各种病害已不能满足设计承载能力和使用要求,影响桥梁的正常和安全运营。针对位于安徽省当涂县某钢筋混凝土双曲拱桥,进行了包括外观检查、混凝土强度检测在内的桥梁现状调查和静载试验研究,其中试验结果表明目前该桥仍然能够满足原有设计承载能力,但是拱肋整体性较差。综合静载试验结果和外观检查,提出相应的维修养护和日常管理建议。同时本次静载试验可作为同类桥梁的试验参考,具有一定借鉴意义。
Along with the rapid socio-economic development, some diseases on the existing bridges in service due to traffic volume growth, design defects and lack of maintenance have failed to meet the design carrying capacity and requirements and affect the normal and safe operation of the bridge. According to the investigation of the bridge status and the static load test, including the appearance inspection and concrete strength test, a concrete double-curved arch bridge in Dangtu County, Anhui Province, the test results show that the bridge is still able to meet the original designed load capacity , But the arch rib integrity is poor. Integrated static load test results and visual inspection, put forward the corresponding maintenance and daily management recommendations. At the same time this static load test can be used as a test reference for similar bridges, with some reference.
