摘要
本文分析了观测数据误差对安全监控模型建立的影响,讨论了异常数据探测的几种方法,研究了对模型推断(参数估计和预测)有显著影响的观测数据诊断原理。分析表明,观测数据对监控模型的影响不仅与测值的精度有关,而且还取决于测值在空间所处的位置。通过对观测资料的数据诊断,将进一步提高大坝安全监控模型的功效。
This paper analyses the influence of survey error on setting up safety determination model, and discusses some probe methods of unusual data. Besides, it studies diagnose principle of observation data with notable influence in setting up model. The results show that the influence of observation data is not only relevant to the accuracy but also to the space place. By using the data diagnose instead of observation data, the safety determination model of dam will be improved.
