摘要
提出了缓和曲线和圆曲线的圆心坐标统一公式 ,用曲线圆心坐标和对称法 ,完整地推导出道路曲线无间断计算 ,中、边桩同时测设的数学模型 ,在实际工作中得到高效利用。
The author has produced the unified formula of circle centre coordinate of miligation curves and circle curves, and has completely deduced the mathmatics model of continuous calculation and designing middle piles and side piles at the same time in road curves with the methods of curve circle centre coordinate and symmetry, which has been adopted effectively in practice.
