vertical ultimate uplift resistance of single pile

In this paper,some buffer operators are applied to modify the primordial non-isometric step GM(1,1) model,on which we have founded the same dimension grey recurrence dynamic model GM(1,1) to predict uplift ultimate bearing capacity of single piles.

采用缓冲序列算子,对原始非等步长GM(1,1)模型作修正,并在此基础上建立了等维灰数递补动态预测GM(1,1)模型对单桩抗拔极限承载力进行预测。
