摘要
路拱曲线参数的选择不仅影响着道路的横向排水、行车安全,也对道路设计时工程量的计算有一定的影响。通过调整路拱曲线参数,计算出路拱曲线和坐标轴围成区域面积的解析值和用割线代替曲线时的计算值,进而分析路拱曲线各参数的选取对工程量计算误差的影响。
The selection of camber curve parameter not only influences the transverse drainage and driving safety of road, but also influences the calculation of engineering quantity in the design of road. By means of adjusting the camber curve parameter, the article calculates the camber curve, and the analyzing value of field area surrounded by coordinate axis and the calculation value in the secant instead of curve so as to analyze the influence of selecting various camber curve parameters on the calculation error of engineering quantity.
