| 摘 要： | 针对多数滑坡监测得到的数据是非等间隔的情况,运用新方法推导出MUGM(1,m)模型。首先用间隙变换后的时间间隔代替原始时间间隔,然后构造新的时间序列,最后根据微分方程推导出预测公式;并以某滑坡体为实例进行建模分析,通过与传统时间加权的方法对比,验证了新方法的预测精度要优于传统方法。

| Abstract: | Most data which have been gotten by landslide monitoring is unequal interval. This paper adopted a new method to deduce the MUGM(1,m)model. At first, it used the transformed time interval to replace the original one, and then constructed a new time sequence, at last, according to the differential equation, it deduced forecasting formulas. What's more, taking a certain landslide as an example to do a modeling analysis and making a comparison with the traditional time weighted method, it proved that the prediction accuracy of new method is much better. |
