摘要
本文提出一种降低拟合曲线外推偏差的方法——渐近线辅助拟合法。将该法用于确定大粒径砂卵石最大干容重,克服了《土工试验规程》推荐的“相似级配模型系列延伸法”以及其它类似方法所普遍存在的外插值偏差较大的问题。
In this paper, a method of curve fitting with asymptotic line is proposed for reducing the error of extrapolation value. This method is applied to determine the max. dry density of coarse grained Sandy gravels to decrease the error existed in extrapolation by means of similar gradation model extension method introduced by Chinese Geotechnical Test Code[1] and the other related method.
