摘要
本文利用双三次曲面拟合建筑场地,保证了各方格间标高和斜率的连续性,对曲面积分并根据平整前后土方量相等的原则,可准确地确定场地设计标高.利用文中所介绍的方法,可以使填挖平衡得到所需要的满足程度,而不增加地形测量的外业工程量.
In this paper, bicubic surface is used to fit construction ground to ensure the continuity of heights and slopes within each net.The design height can be determined accurately by integrals of the surface.With the method introduced, the principle of equalling the earthwork before and after levelling can be satisfied without increasing the work on out-door survey.
