| 摘 要： | 首先假设边坡滑坡体为刚体,建立了边坡滑坡的动态模型,用变形后的监测点和基准点上的GPS载波相位观测值组成双差观测值,提出一种滑坡监测的卡尔曼滤波模型.建立的模型不仅利用了包含在观测中的统计信息,而且利用边坡滑坡的有关力学状态和地质条件所提供的信息.最后,以一实例论证了方法的可行性.

| Abstract: | This paper fist assumes that the landslide object is a rigid,sets up a dynamic model of landslide,forms double difference observation data by using the GPS carrier phase observation data on monitoring point after deformation and base point,proposes a Kalman filter model of landslide monitoring.The model of this paper used not only statistical information included in observation,but also the information provided by related dynamic state and geological condition of landslide.Finally,the feasibility of the method is proved by a practical example. |
