摘要
本文分析了传统无缝桥的结构原理和特点,提出了新形式全无缝桥的设计思路并运用到实际工程中,通过对通惠河桥进行无缝结构形式优化后,主要从接线道路的计算和分析中论述新型全无缝桥的设计特点,从而验证工程采用全无缝结构的合理性,为我国无缝桥技术的发展提供参考。
Starting from the causes of expansion joint diseases,this paper analyzed the structural principles and characteristics of traditional seamless bridges,puts forward the design ideas of new full seamless bridges and applies them to practical projects.After optimizing the seamless structural forms of Tonghui River Bridge,this paper mainly discussed the design features of new full seamless bridges from the calculation and analysis of connection roads,thus confirming the application of full seamless structure in engineering.The rationality provides reference for the development of seamless bridge technology in China.
