夷桥路改扩建线形拟合方法分析

Application Analysis of Linear Fitting Method in Yiqiao Road Reorganization and Expansion Engineering

结合宜昌市夷桥路设计案例,分析市政道路改扩建中平面线形拟合中“综合法”的理论和纵断面线形拟合设计中最小二乘法的拟合效果。结果表明,市政道路改扩建设计中,综合法和最小二乘法可以较好地得到符合要求的平曲线和竖曲线,应用效果良好。

Combined with the design case of Yiqiao road reorganization and expansion engineering in Yichang city,paper analyzes the theory of "comprehensive method" in municipal road reorganization and expansion engineering,and the effect of least square method in profile line fitting design.The results show that,in municipal road reorganization and expansion engineering,"comprehensive method" and least square method can get horizontal and vertical curves meeting specification requirements,and the effect application is super.
