基于现代公路桥梁结构耐久性技术分析
|
摘要
我国公路桥梁不仅在数量上还是在规模上都取了巨大成就,随着港珠澳大桥、北盘江大桥等特大桥梁的建设取得成功后,高墩柱桥梁,跨江跨河桥梁等具有技术挑战的桥梁对我国桥梁建设者已经不是问题了。随着公路桥梁建设的快速发展,人们更加越来越重视高速公路的耐久性、行车舒适性等使用性能了,反观我国桥梁投入使用后的病害调查统计,设计中的结构耐久性技术问题已成为现代公路桥梁的核心问题。本文将结合工程实践调查与试验研究就现代公路桥梁的结构耐久性技术做出分析。希望对桥梁耐久性技术现象及其他桥梁病害处理提供应用研究参考。
China's highway bridges have made great achievements not only in quantity but also in scale. with the success of the construction of super-large bridges such as hong kong-Zhuhai-Macao bridge and north panjiang bridge,high pier-column bridge and cross-river bridge are no longer problems for our country's bridge builders. With the rapid development of highway bridge construction,people pay more and more attention to the durability of the highway,driving comfort and other performance,in contrast,China's bridge put into use after the disease investigation,the design of structural durability technology has become the core problem of modern highway bridges. In this paper,the structural durability technology of modern highway bridges will be analyzed based on engineering practice investigation and experimental study. It is hoped to provide a reference for the application research of bridge durability technology and other bridge disease treatment.
