互通式立体交叉匝道起终点标高及纵坡计算方法的探讨

Further Discussion on Starting-Terminal Point Elevation and Slope Calculation Method of Interchange Ramp

结合工程实际,探讨一种新的互通立交匝道起终点标高及接坡计算方法。分析传统方法的弊端,运用最小二乘法,对主线端每延米数据进行分析,拟合匝道起终点标高及纵坡,研究出一种新的设计思路。

Combined with the engineering cases, the article further discusses a new starting-terminal point elevation and slope calculation method of interchange ramp, analyzes the disadvantages of the traditional methods, and analyzes each linear meter data at the end of main line by the least square method. A new design thinking is studied by fitting the elevations and slopes at the starting and terminal points of ramp.
