分离法校正复曲线及程序设计

Correcting Combined Curve by Separating Method and Programming

校正复曲线一般需要绘角图以分析判定其所含子曲线的个数及子曲线间的缓和曲线长度。这既费事又不够精确。本文提出的分离法校正复曲线，只需输入外业测量资料而不绘角图，便可由电算程序自动判定子曲线的个数，并顺序逐个优选子曲线半径，以及计算子曲线各测点的拨距量。方法简单明了，计算结果甚为满意。

In correcting combined curves, as a general rule, it is necessary to draw an an gle figure (denective angle～distance curve) so as to determine the subcurve's number con sisting of the combined curve and the length of the transition curve between the subcurves That is not only troublesome but also potentially inaccurate. This paper offers another method for correcting combined curves with which one need only to input the measurink data and need not to draw an angle figure. The program designed for correcting the on bined curve will determine the subcurve's number automatically, will select the optimon radius and calculate the moving amount of every measuring point for each subcurve succes sively. This method is simple and clear. The calculating result is quite satisfactory
