一种简便实用的平面线形曲线定线法

摘要

A simple method about alignment of horizontal curve isintroduced. This method is faster and attains standards in the paper location of horizontal curve in difficult terrain. Compared with accumulate element alignment method and apartment curve alignment method, it takes only 1/3～1/5 of their time to use the simple method of alignment to determine a horizontal curve. This method is faster and more efficient than that of the two methods above.%介绍了一种简要的曲线定线法，该方法在进行地形地物困难地段的平曲线纸上定线过程中，定线速度快，计算和定线精度完全能满足纸上定线阶段的精度要求．与过去常用的积木法和线元法曲线定线相比，简要曲线定线法确定一个平曲线所需的时间一般仅为积木法或线元法的1/3～1/5，大大节约了定线的时间，提高了纸上定线阶段的作业效率．
