Using grey system theory approach this paper has developed grey model for reservoir sedimentation on the basis of the time series of accumulative amount of deposition in Toutunhe reservoir. The GM has gived the predicted values from 1979 up to 1994. The calculated values obtained from the GM agree well with the field measurements.

本文以头屯河水库泥沙淤积的时间序列数据为依据,应用灰色系统理论,建立了水库泥沙淤积的灰色动态模型,得到了累积淤积量的变化规律,提出了直到1994年的累积淤积量的预测值。1989年以前的模型计算值与实测值吻合良好。

This paper applies the Grey-System theory and method to dispose the squirm data observed from May 1987 to May 1989 for the front deep layer of Xintan slide. It is considered that the front of Xintan slide is at the stage of stable squirm after the big slide in June 1985. This paper also investigates the possibility of using the Grey-Model to slide predication.

本文运用灰色系统理论方法,处理了1987年5月至1989年5月新滩滑坡前缘深层蠕变观测资料,初步认为:目前新滩滑坡前缘(深层)处于1985年6月大滑坡后的调整稳定蠕变阶段。此外,对灰色模型用于滑坡预报的可能性进行了探讨。

Based on practice, an unequal intcrval grey forecasting model—GM(1,1) is proposed. It overcomes the disadvantages of equal interval grey model that requires the initial data successive. The actual data of landslide's displacement measured at Bikou power station from 1982 to 1989 (1987 absent) are used to test this new model, and the result shows theoretical values have only a little difference—under 5 mm from actual data. Then, with this new model, we obtained the forecasting values of the...

Based on practice, an unequal intcrval grey forecasting model—GM(1,1) is proposed. It overcomes the disadvantages of equal interval grey model that requires the initial data successive. The actual data of landslide's displacement measured at Bikou power station from 1982 to 1989 (1987 absent) are used to test this new model, and the result shows theoretical values have only a little difference—under 5 mm from actual data. Then, with this new model, we obtained the forecasting values of the annual average accumulative horizontal displacement of these three measured points after 1989, that is from 1990 to 2005, and pointed out the possible sliding time of this landslide. So this new model is proved to be very useful for engineering practice.

本文根据需要,提出了不等时距的灰色预测GM(1,1)模型,它克服了等时距GM(1,1)预测模型要求原始数据列连续的缺陷。用提出的模型对碧口水电站右坝肩滑坡体从1982年到1989年(1987年空缺)的实际观测资料进行预测,所得结果与实测值误差均在5 mm以下,并用此模型预测了1990年到2005年三个监测点的水平位移年平均累计值及相应的年均速率,指出了该滑坡体可能滑动的年限,为工程实际提供依据,具有重要的意义。
