经济的快速发展促进了高速公路里程的显著增长,病害及缺陷在高速公路中普遍存在,难以适应目前高速公路的迅猛发展。在加固改造高速公路桥梁的建设中,虽然桥梁产生的病害及缺陷各不相同,但或多或少存在共性的原因。应用先进材料及成熟的现代施工技术,在加固与改造桥梁的过程中,可以归纳总结多种卓有成效的方法,使桥梁使用功能得以恢复,确保高速公路实现顺畅的交通。
The rapid economic development has promoted the remarkable growth of the expressway mileage. The diseases and defects are ubiquitous in the expressway and it is difficult to adapt to the rapid development of the expressway at present. In strengthening the construction of the highway bridge construction, although the bridge disease and defects are different, but more or less common reasons. The application of advanced materials and mature modern construction technology, in the process of reinforcement and transformation of the bridge, can summarize a variety of effective methods to enable the bridge to be restored to ensure the smooth use of the traffic.
