| 摘 要： | 根据道路线形的特点，为了便于测设中桩坐标，建立了一种道路中桩坐标测设的通用模型，并给出了中桩坐标测设的通用公式，其不仅适用于直线元、圆曲线元，还适用于缓和曲线统一坐标的计算，尤其是立交匝道中用于连接两不同半径圆曲线的不完整缓和曲线的计算。

| Abstract: | According to the characteristics of the road alignment,in order to survey and design coordinates of center-stake easy,establish a general model of survey coordinates of center-stake,and gives a generic formula,which applies not only to a straight-line element,round curve element,also applies to coordinate a unified curve calculation,especially in the interchange ramp to connect the two different circular curve radius curve incomplete calculations. |
