摘　　要：根据滑坡位移随时间逐次变化的规律,建立滑坡位移演化的逐代遗传模型,求解滑坡每代的位移和稳定系数。在此基础上对沪蓉西高速公路湖北宜昌-恩施段古树屋滑坡的位移变化进行了分析,结果表明,该模型的位移计算值结果较为理想,且简单可行,并通过对稳定系数的研究提出了滑坡稳定性判断的一个新依据。According to the relation of landslide displacement time series, the stepwise inherited model is presented and applied to calculate the displacement and stable coefficient of every step for the landslide. Then the model is applied to Gushuwu landslide of Hu-Rong Expressway in Hubei Province. The results show that the displacement calculated by the model is perfect and this method is much easier to operate; and a new basis is presented according to the stable coefficient.
