《公路》1990年3月号刊登的李鲁卿同志“用公路曲线测设用表求虚交点”一文,对于解决虚交圆曲线与基线相切的情况来说是大有帮助的,这种方法常称之为“切基线法”,或称“同半径复曲线”和“双交点单曲线”的计算法。它是测设虚交点时的一种 The article “Highway” published in March 1990 by Comrade Li Luqing, “Using Intersections of Highway Curves to Find a Void,” is of great help to solve the situation where the imaginary circle is tangent to the baseline. This method is often helpful Called the “cut baseline method”, or “complex radius with the radius” and “double-point single curve” calculation method. It is a set of virtual intersection point when a
