摘　　要：建筑物的中心轴线构成空间曲线,要依据曲线上有限个观测点的坐标,计算曲线的弯曲度,用以估算建筑物的弯曲程度。文章建立起空间曲线的三种弯曲度指标。给出了能直接利用原始数据计算平均弯曲度的公式;设计出以极大化搜索为基础的求投影弯曲度的方法;构建了以最佳圆弧拟合为特征的估算整体弯曲度的方案。最后,对三种弯曲度的特点和走势进行了分析比较。Central axis of the building constitutes space curve. This paper calculates the bending curve to es- timate the degree of bending of according to the coordinates of the limited observation points on the curve. This article establishes three bending degree index of space curve. It gives the average curvature of the for- mula directly using the original data; and it has designed projection curvature ways based on maximization search; and sets up overall curvature of the program characterized by best fit arc. Finally, the three bending characteristics and trends are analyzed and compared.
