胶接缝节段预制拼装桥梁理论研究综述

节段预制拼装造桥技术是近年来国内新发展起来施工技术,环氧树脂胶接缝也是目前国内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,但国内学者在该领域理论研究较少。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；并且针对胶接缝节段预制拼装桥梁目前理论研究的空白,提出在环氧树脂胶接缝的寿命、剪力键的设计、桥梁结构体系的设计等方面做进一步深入研究。

The Summary of Research on Precast Segmental Assembling Bridges with Epoxy Resin Joints

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, domestic scholars have little theoretical research in this field. In this paper, the research status of epoxy resin joints, shear keys and durability of precast segmental assembling bridges with epoxy resin joints is summarized. And some deficiencies in the present research are pointed out. In view of the blank of the current theoretical research on the precast segmental assembling bridges with epoxy resin joints, further research on the life of epoxy resin joints, the design of shear keys and the design of bridge structure system is proposed.
