摘要
本文指出线性化后的曲线拟合参数不是无偏估计量.对此,作者用牛顿(Newtom)法和麦夸尔特(Marquardt)法对曲线回归方程系数进行优化,提高了曲线拟合精度.通过实例计算,说明此法用于建筑物的沉降分析效果显著.
This paper points out that the linearized curve-fitting parameters are not unbiased estimations. For this, reason the authors adopted Newton and Marquardt method to optimize the coefficients of curve regression epuations, the precision of the curve fitting being improved By case histroy calculatrons, it manifests that this method is evidently effective in the application of building settlement analysis.
