【摘要】：和全国其它省区相比,青海省干线公路发展仍然处于较低水平,还不能满足社会经济发展和人民生活水平提高的需要。青海省“十二五规划纲要”指出需要提高公路等级,构建“六纵九横二十联”。214国道是青海省规划的高速公路网“3410”南北纵线中的“一纵”,是连接青海、西藏、四川、云南四省区的干线公路,对加强西部边缘省区连接、强化西部出行能力起着十分重要的作用。因为沿线冻土融沉、冻胀、不良水文地质及重载车辆的影响,214国道出现了路面龟裂、纵横裂缝、路基路面沉陷、边坡溜塌、桥涵沉降变形等多种病害。因此,开展对青海省214国道高等级公路改扩建建设方案的研究具有重要意义。本文首先选取青海省214国道共和至结古公路段作为研究对象,详细阐述了该公路段地理位置、气候、水文和地质条件等,综合分析了214国道经过区域(海南州、果洛州、玉树州)环境特征和交通状况,为将来214国道的改扩建提供有用的参考资料；然后,对214国道高等级公路进行交通量预测,远景年(2030年-2034年)交通量将达到四车道高速公路的适应范围,并综合分析了既有公路的适应性；接着,对现有214国道的使用状况进行调研,发现既有公路的病害已严重影响了公路的正常运行,降低了公路的服务质量,急需进行病害整治；最后,从设计速度、路线、路基路面、桥涵、封闭与辅道、环境保护等不同角度,提出了具体的改扩建方案。
[Abstract]:Compared with other provinces and regions in China, the development of trunk roads in Qinghai Province is still at a low level, and can not meet the needs of social and economic development and the improvement of people's living standards. The outline of the 12th Five-Year Plan of Qinghai Province points out that it is necessary to raise the grade of highways and build "six columns, nine horizontal and twenty links." the 214th National Highway is the "first vertical" of the highway network "3410" in Qinghai Province, which connects Qinghai, Tibet, and Sichuan. The trunk roads in the four provinces of Yunnan play a very important role in strengthening the connection between the provinces and regions on the edge of the west and strengthening the travel capacity of the western regions. Due to the influence of thawing, frost heaving, bad hydrogeology and heavy load vehicles along the freeze-soil, there are many kinds of diseases such as pavement crack, longitudinal and horizontal cracks, subgrade and pavement subsidence, slope slip and collapse, bridge and culvert settlement deformation and so on. Therefore, it is of great significance to study the reconstruction and extension scheme of Highway 214 in Qinghai Province. In this paper, the highway section from Gonghe to Jiegu of No. 214 State Road in Qinghai Province is selected as the research object, the geographical location, climate, hydrological and geological conditions of the section are described in detail, and the region through which National Highway 214 passes (Hainan State, Guoluo County) is analyzed synthetically in this paper. Yushu) the environmental characteristics and traffic conditions provide useful reference materials for the reconstruction and expansion of National Highway 214 in the future; then, the traffic volume of Highway 214 is forecasted. The traffic volume in the prospective year (2030-2034) will reach the adaptation range of the four lane expressway, and the adaptability of the existing highway will be comprehensively analyzed. It is found that the diseases of the existing highway have seriously affected the normal operation of the highway, reduced the service quality of the highway, and urgently need to be remedied. Finally, from the design speed, route, roadbed and pavement, bridge and culvert, closed and auxiliary roads, Environmental protection and other different angles, the specific reconstruction and expansion program is put forward.
