状元沟桥病害分析及加固改造方案设计

Disease Analysis and Reinforcement Scheme Design of Zhuangyuangou Bridge

状元沟桥在服役多年后,其上部结构以及下部结构均出现裂缝以及混凝土剥裂等病害,并且已不能满足现阶段的交通使用要求。针对状元沟桥出现的上述问题,首先调研了状元沟桥的所有病害以及分析其产生病害的原因;其次,对状元沟桥产生的这些病害的原因进行分析,提出相应的加固维修改造设计方案;对每种加固维修改造设计方案的施工要点进行详细阐述,并对这种加固施工方式产生的经济效益以及社会效益进行了阐述;最后该维修加固改造效果明显,提升了状元沟桥的使用性能。

After years of service, the superstructure and substructure of Zhuangyuangou bridge have cracks, concrete peeling and other diseases, and can no longer meet the traffic requirements at this stage.In view of the above problems of Zhuangyuangou bridge, firstly, all the diseases of Zhuangyuangou bridge are investigated and the causes of the diseases are analyzed;Secondly, the causes of these diseases of Zhuangyuangou bridge are analyzed, and the corresponding reinforcement, maintenance and reconstruction design scheme is proposed;The construction points of each reinforcement, maintenance and reconstruction design scheme are described in detail, and the economic and social benefits of this reinforcement construction method are described;Finally, the maintenance, reinforcement and reconstruction effect is obvious, and the service performance of Zhuangyuangou bridge is improved.
