摘要：伸缩缝作为桥梁结构中的关键组成部分，对于保证桥梁在温度变化、车辆荷载等因素作用下的正常使用具有重要作用。本文旨在研究公路桥梁伸缩缝的施工技术，通过对伸缩缝的类型、材料选择、施工工艺等方面进行深入分析，提出一套科学合理的伸缩缝施工技术方案。结合实际工程案例，验证所提出的伸缩缝施工技术方案的可行性，为今后公路桥梁伸缩缝的施工提供技术支持。通过本文研究，为提高公路桥梁的安全性提供技术保障，对于推动我国公路桥梁建设的发展具有重要意义。
Abstract: Expansion joints, as a key component of bridge structures, play an important role in ensuring the normal use of bridges under factors such as temperature changes and vehicle loads. This article aims to study the construction technology of expansion joints in highway bridges. Through in-depth analysis of the types, material selection, and construction processes of expansion joints, a scientific and reasonable construction technology plan for expansion joints is proposed. Based on actual engineering cases, the feasibility of the proposed expansion joint construction technology scheme is verified, providing technical support for the construction of expansion joints in highway bridges in the future. The study provides technical support for improving the safety of highway bridges and is of great significance for promoting the development of highway bridge construction in China.
