跨高速公路旧桥拆除工程难点及对策研究

Research on difficulties and countermeasures of demolishing old bridge across expressway

我国交通基础设施建设快速发展,越来越多的桥梁已不能适应目前的交通发展,因此需采取拆除处理。为了探究适用于上跨高速公路旧桥的安全高效拆除施工工艺,以旧桥拆除实际工程为背景,详细的分析了跨高速公路旧桥拆除工程中的难点,在保障桥下高速公路交通安全和施工安全前提下,采取经济合理的拆除施工方案。这些施工方法保证了施工质量和经济社会效益,可为此类工程提供借鉴。

With the rapid development of transportation infrastructure in China,more and more bridges can not adapt to the current traffic development,so they need to be demolished.In order to explore the safe and efficient demolition construction technology for the old bridge crossing the expressway,this paper takes the actual project of the old bridge demolition as the background,analyzes the difficulties in the demolition project of the old bridge across the expressway in detail,and takes the economic and reasonable demolition construction scheme under the premise of ensuring the traffic safety and construction safety of the expressway under the bridge.These construction techniques ensure the construction quality and economic and social benefits,which can provide reference for such projects.
