混凝土坝位移的季节周期趋势分析法

Period-trend Analysis on Conerete Dam Displacement

随着大坝变形观测技术的发展,人们越来越重视变形观测资料的分析研究。混凝土坝位移的季节周期趋势分析法是对大坝变形资料分析处理的新方法。这种方法对具有周期,趋势性变形混凝土坝的实测资料进行分析研究,建立季节周期趋势模型以后,再用新观测资料不断修正模型进行滑移式预测预报、精度较高、效果理想。

With the developement of dam observation technique, engineers are interested in the study of displacement observation analysis and reasonable explanation for the observation. The mathematic model of concrete dam displacement trend is established, considering reservoir level fluctuation, tem-perture, time effect and other factors. With this model, concrete dam can be safely monitored and the dam displacement can be forecasted. The model with periodic observations contiunally modified with new ones will provide for sliding type forecast of the dam displacement. The advantage of this method possesses simplicity, less calculation and high accuracy.
