新型铰缝设计及增强技术研究

Research on New Hingejoint Design and Reinforcement Technology

近年来,随着我国城市化进程的不断推进,桥梁建设行业得到了飞速发展。铰接空心板梁桥具有结构简单、建筑高度小、成本低、自重小等优势,它可以进行批量工厂化预制,施工方便,在中小跨径桥梁中得到了广泛应用。然而,随着交通量的日益增大,在多种因素综合影响下,装配式空心板梁桥的病害问题日益凸显。为了克服传统铰缝无法有效振捣及抗裂性能差等缺陷,本文提出一种新型的铰缝形式,并探讨了相关铰缝增强技术。

In recent years, with the continuous advancement of urbanization in China, the bridge construction indus try has developed rapidly. The articulated hollow slab bridge has the advantages of simple structure, small building height, low cost, and low self-weight,which can be prefabricated in batches and convenient to construct,and is widely used in small and medium span bridges. However, with the increasing traffic volume, under the comprehensive influ ence of various factors, the disease problem of fabricated hollow slab bridges has become increasingly prominent.In order to overcome the defects that traditional hinge joints could not be effectively vibrated and have poor crack resis tance, this paper proposed a new type of hinge joint and discussed related hinge joint reinforcement technologies.
