摘要
本文研究了坝体安全监测中动态模型的建立以及在资料分析中的应用。利用动态平差的成果,根据卡尔曼滤波原理,建立的动态模型,不仅能较确切地描述坝体活动规律,而且反馈了坝体在各种变化着的外界条件作用下的动态特性。此外,分析了动态初始模型选定方法、状态向量初值X(o)和方差Dx(o)的确定等有关问题。
This paper studies a method of dynamic model of the dam safety monitoring and its application in data analysis. Depending on the result of dynamic adjustment and on the theory of Kalman Filtering, dynamic model can describe not only the rule of dam movement, but also feed back dynamic properties with the action of various external conditions. Moreover, this paper analyses the chosen method of dynamic initial model, state vector's initial value x(o) and variance Dx(o).
