摘要
随着经济的快速发展,道路交通出行量日益增大,某些早期建成的高速公路开始出现交通客流量滞留的拥堵现象,因此,近年来,国家对高速公路的扩容改建非常重视。论文以实际工程项目为依托,通过对平纵面道路现状进行调查分析,理出扩容线型拟合设计的新方案思路,将平面和纵面测点位的测量校差控制在标准允许范围内,提出合理的路线线型拟合设计方案。
With the rapid development of economy, people’s traffic volume is increasing day by day, and some early-built highways begin to appear traffic congestion phenomenon. Therefore, in recent years, the state attaches great importance to the expansion and reconstruction of expressway capacity. Based on the actual engineering project, through the investigation and analysis of the present situation of road plan and vertical section, a new scheme for the fitting design of the expansion line is worked out, and the measurement error of the plane and longitudinal measuring points is controlled within the allowable standard range, a reasonable design scheme of alignment fitting is put forward.
