胶接缝节段预制拼装桥梁理论研究综述

Summary of Precast Segmental Assembling Bridges with Epoxy Resin Joints

节段预制拼装造桥技术是近年来中国新发展起来施工技术,环氧树脂胶接缝也是目前中国新兴的装配式桥梁连接方式,虽然在一些桥梁项目上进行了试点,但学者们在该领域理论研究较少。为此,针对胶接缝节段预制拼装桥梁的主要结构:胶接缝、剪力键以及结构的耐久性的研究现状进行了归纳总结,指出了目前研究中存在的若干不足;针对胶接缝节段预制拼装桥梁目前理论研究的空白,提出了在环氧树脂胶接缝寿命、剪力键设计、桥梁结构体系设计等方面开展深入研究的建议;可为今后节段预制拼装桥梁的深入研究提供理论依据。

The technology of precast segmental and assembling bridges is a newly developed construction technology in China in recent years. Epoxy resin adhesive joint is also a emerging prefabricated bridge connection in China. Although it has been piloted in some railway transportation industries, scholars have less theoretical research in this field. The research status of the main structures of durability of precast segmental assembling bridges with epoxy resin joints: epoxy resin joints, shear keys and structural durability were summarized, and some deficiencies in the present research were pointed out. In view of the blank of the current theoretical research on the precast segmental assembling bridges with epoxy resin joints, suggestions on further research on the life of epoxy resin joints, the design of shear keys and the design of bridge structure system were proposed. It can provide theoretical basis for further study of precast segmental and assembling bridges.
