通定高速公路两阶段施工图设计方案研究

通过研究通渭至定西高速公路项目,总结其项目概况,分析调研线路经过区域的地形地貌、滑坡、地震、气候特征对其的影响,有针对性地对古滑坡路线(K12+500—K12+800)和宁远镇过境段(K47+300—K50+000)路线的初步设计方案与施工图方案进行基于路线、路基、路面、桥梁、隧道和交叉等方面的比选,进而得出最佳施工方案,以期为类似工程提出借鉴方案。

Based on the Tongwei to Dingxi Expressway,this paper summarizes the general situation of the project,and analyzes the influence of geomorphology,landslide,earthquake and climate characteristics of the area through which the route passes through through the field investigation.Targeted to the ancient landslide route scheme(K12+500~K12+800)and Ningyuan town transit route scheme(K47+300~K50+000)of the preliminary design scheme and construction drawings of the route,roadbed,pavement,bridge,tunnel,cross aspects of the best construction scheme,in order to put forward a similar project reference scheme.
