浅析既有高速公路平面线形拟合设计

Analysis of Plane Alignment Fitting Design of Existing Expressway

为了保证高速公路路面大修的平整度要求,提升公路技术状况评定指标,采用纬地道路设计软件对公路平面线形进行拟合优化设计。采用科学的方法对原有线形进行测量,以实测数据为基础,采用交点设计法进行公路平面线形拟合。结果表明,本文提出的针对既有高速公路调坡过程采用平面线形拟合的方法,可以优化设计数据,并为施工阶段提供精准的数据支撑,极大地提高了工作效率。

In order to ensure the smoothness requirement of highway pavement overhaul and improve the evaluation indicators of highway technical conditions,the highway plane alignment fitting design was optimized by using Hintsoft design software.The original alignment was measured by scientific method,and the road plane alignment was fitted by intersection design method based on the measured data.The results show that the method proposed in this paper can optimize the design data,provide accurate data support for the construction stage and greatly improve the work efficiency.
