摘 要:经济的快速发展对于我国国内的交通提出了更高的要求。规划与布局山区高速公路网络是打通我国公路交通瓶颈的关键一环,同时也是带动山区经济发展的重要战略布局。高速公路桥梁作为山区高速公路建设中的重要组成部分对于高速公路建设有着极为重要的意义。由于山区地形条件、地质以及水文条件等都与平原地区有着明显的差异从而对山区高速公路桥梁的设计建设带来了不小的难度。文章在分析山区高速公路桥梁设计关键点的基础上对如何做好山区高速公路桥梁设计优化进行了分析阐述。

Abstract: The rapid development of economy has posed higher requirements for domestic traffic in our country. The planning and layout of highway network in mountain areas is not only a key link to break through the bottleneck of highway traffic in our country, but also an important strategic layout to promote the economic development of mountain areas. As an important part of mountain highway construction, highway bridge is of great significance for highway construction. Because the topographic conditions, geological and hydrological conditions in the mountain area are obviously different from those in the plain area, which brings great difficulty to the design and construction of highway bridges in the mountain area. Based on the analysis of the key points of highway bridge design in mountain area, this paper analyzes and expounds how to optimize the design of highway bridge in mountain areas.
Keywords: mountain highway bridge; design; optimization
前言
我国地形结构分明,东部沿海及中部地区主要以平原为主,而西南地区、黄土高原等区域则主要以山区丘陵为主。长期以来受交通影响上述区域经济发展明显滞后。在十三五规划中国家将上述区域高速建设列入了规划,以交通带动当地经济发展。山区高速公路桥梁是高速公路建设中的重点,尤其是在上述地形、水文、地质等都较为复杂的区域,为保证山区高速公路桥梁建设质量需要做好山区高速公路桥梁的设计工作。
1 山区高速公路桥梁设计总原则
山区高速公路桥梁面临的环境更加复杂从而对山区高速公路桥梁设计提出了更高的要求。在山区高速公路桥梁设计中需要对桥梁结构安全性、构造处的科学……
