摘要
该文论述了以缓和曲线平行线为边界的地块面积的计算特点,推出了缓和曲线或其平行线弓形面积的严密计算公式,讨论了已知缓和曲线平行线弧长或坐标值计算弓形面积的问题,给出了相应的算例。
This paper briefly introduces the area calculation problem of a block, the boundary of which includes the easement curve or its parallel curve. The rigorous formulae for calculating the segment area of the easement and its parallel are derived in detail. Finally , the problems about the computing segment area by using arc length or coordinates of the parallel to easement are also discussed.
