It is revealed that the computation value in theory is greatly different from the monitoring one , by analyzing a group of practical monitoring data of deep soil deformation 通過對某實測工程地基分層沉降監測數據的研究,發現理論計算值與實測值有較大差距。
The results indicate that this comprehensive kalman filtering technique has the features of good stability of computation values , rather strong adaptability and well elimination of the effect caused by gross errors 算例結果表明,這種綜合卡爾曼濾波方法具有數值穩定性好、有較強的自適應性和能比較好地削弱粗差影響等優點。
In the paper , with system energy balance method and heat conductive equations , on tne basis of short time heat transfer modeling established the long time modeling , considering heat interference in thermal well group . this paper used the finit element method for element division and computer analysis , and provided the operation temperature figure . acquired computation values agreed well with experimental results , the most difference between them was 5 . 13 % 本文采用系統能量平衡結合熱傳導方程,在淺埋套管式換熱器短期傳熱模型基礎上建立了長期傳熱模型,并考慮了管群熱干擾對模型的影響。并運用有限單元法軟件編程進行離散和計算機分析,得出模擬溫度場,其模擬值與實測的均值基本相符,兩者最大誤差小于5 . 13 % ,表明該模型具有一定的合理性和實用意義。
