| 摘 要： | 通过对完整缓和曲线参数方程进行分析,构建了以缓和曲线上任意一点为坐标原点的切线直角坐标系,进而推出完整、非完整缓和曲线的切线直角坐标通用计算公式。结合VB程序设计界面友好以及Matlab数值积分运算函数精度较高的特点,设计实现了缓和曲线坐标计算程序,并根据某高速公路工程中的匝道设计数据,利用该程序对匝道中的缓和曲线坐标进行了计算,检验了程序的准确性和可靠性。

| Abstract: | Based on the analysis of complete easement curve＇s parameter equation, a tangential rectangular coordinate system whose coordinate orign can be any point on the curve was built. Then the common formula for calculating the complete and incomplete easement curve＇s tangential rectangular coordinate was ascertained. A program for the co ordinate calculation of easement curve which combined the friendly programing interface of VB and the precision in tegral operation of matlab was designed and achieved with the programming language of VB and Matlab. With the designed data, the coordinate of easement curves in a freeway ramp project were calculated, which verified the accu racy and reliability of the program. |
