摘要
利用曲线拟合的最小二乘法原理,确定沙土在某垂直压力下的抗剪强度与干密度的关系,并绘制曲线图,从而避免了人工处理数据的任意性,减小了误差。
Making use of the principle of least square method for the fitting of the curves, this paper determines the relation between the shear strength and the dry density of the sandy soil under a certain vertical pressure, and skeletonizes the curvilinear figure, avoiding the random of artificial processing the data and reducing the errors.
