【摘要】 通常疏浚工程中挖槽土方量计算模型的河床横断面是通过测量点的特殊断面 ,该断面轮廓曲线假定为近似直线或折线 .本文的算法是先基于测量坐标生成河床曲面函数 ,求出任意的河床横断面曲线 ,以该曲线代替近似直线或折线计算挖槽土方量 ,提高了计算精度更多还原

【Abstract】 In calculation models of cutting volume for dredging project,the cross section is usually a special one through survey points,and the curve of the river bed is assumed to be a line or a polyline.This paper gives a new calculation method,which firstly produces the river bed toroidal function based on survey points coordinates,then works ont the bed curve function of the cross section and calculates volume of cutting through this curve instead of the line or the polyline.This method improves the precision for cutting volume,calculation.更多还原
