| 摘 要： | 考虑到处于不同位置的滑坡变形监测点,由于它们所处的位置不同,各种环境因素对它们的影响及影响程度也不同,因此它们的变形规律也不同.首先通过计算比较找出剩余标准差最小的变形与时间、大气降雨量、温度相关关系的单因子模型,再将这些单因子模型通过叠加,组成多因子模型,然后将变形与时间、大气降雨量、温度相关关系的多因子模型的模型参数看作含有动态噪声的状态向量,建立卡尔曼滤波模型.实例计算表明这种建模方法效果较好.

| Abstract: | Considering landslide deformation monitoring points in different locations,because they are in different location,it is different that all environmental factors influence them and influence extent to them,so their deformation laws are different.Firstly,the single factor model that deformation is interrelated with time,rainfall,temperature whose residual standard deviation is least is found by calculation and comparison,and these single factor models are superimposed to form a multi-factor model,then paramet... |
