Through fitting with constant parameters or parameters time-dependent with data of direct shear creep experiments on marble, we conclude that:1. The results of fitting with constant parameters with data of samples which have no creep phase of acceleration are good.
本文在Burgers元件模型的基础上通过对大理岩、板岩直接剪切蠕变实验数据进行定常参数拟合分析与非定常参数拟合分析，得出了以下结论：1．定常参数拟合对于不发生加速蠕变的试样可以取得较好的拟合效果，但是拟合误差较大，特别是在稳定蠕变阶段蠕变速率很小的情况下。
