摘    要:用正交函数曲线拟合法计算土方开挖体积。与目前常规采用的梯形法、Simpson法及三次样条函数法等插值类计算方法相比,当划分的测设格网对计算不利及测点读数存在较大的误差时,拟合法的计算精度明显高于其它各类方法。而当格网划分比较适当时,本文方法仍有较好的精度,能够满足实际工程计算要求,且拟合法程序结构简单。

关 键 词:正交函数,曲线拟合,土方量,测设格网

Abstract:The use of quadrature function curve fitting in excavation volume calculation of earthwork wasdiscussed. When the division of measurment grid is unsuitable to the calculation and errors exsit inelevation of station points,this methed occupys higher precision, compared with interpolation meth-ods,such as trapzied methed,Simpson methed and cubic spline function methOd etc. For other di-visions of measurement grid,the methed discussed in this paper also occupys higher precision andsuffice to meet the demand of calculation in practical engineering.
Keywords:Curve fitting  Earthwork  Measurement grid  Precision
