| 摘 要： | 提出采用多层建模法预报边坡位移。该方法把动态系统的状态(或输出)预报问题分为系统的时变参数预报和在此基础上对系统的状态(或输出)预报两部分，可充分考虑被预报系统的时变特性。给出了多层递阶的建模和预报方法。工程实例表明该方法有较好的预测精度和实用价值。

| Abstract: | The method of multi-layer recursive modeling for predicting slope displacements is presented. The state (output) forecast of the dynamic system is divided into time variable forecast and state (output) forecast based on the former. The time variable characteristics in the forecast system can be fully considered. The modeling of multi-layer recurrence and the forecast method are presented. The engineering example shows that the method has better precision and practical values. |

| Keywords: | slope multi-layer recursive method time variable forecast state forecast |
