在对清江隔河岩水库库岸5个滑坡体进行稳定性监测工作的基础上,总结出3种不同类型的滑坡位移曲线:平稳型变化曲线、发展型变化曲线、收敛型变化曲线,并提出了相应的位移数学模型。初步认为:平稳型变化曲线采用线性函数来拟合,发展型变化曲线采用灰色理论建立GM(1.1)模型来拟合,收敛型变化曲线采用对数函数来拟合。位移模型的建立有助于对各滑坡体趋势性位移进行定量分析和中短期预测并能直接或间接地反映出滑坡体变形的总趋势,分析了清江库岸5个滑坡体各自位移特征及发展趋势,为水库蓄水及库区移民和当地政府防灾决策提供科学依据。
Based on the stability monitoring of five landslides in Geheyan reservoir bank of Qingjiang River, three different types of landslide displacement curves are summarized: steady type, development type and convergence type, and put forward The corresponding displacement mathematical model. It is preliminarily considered that the steady curve is fitted by a linear function, the developed curve is fitted by GM (1.1) model with gray theory, and the convergent curve is fitted by a logarithmic function. The establishment of the displacement model is helpful for the quantitative analysis of the displacement of landslides and the prediction of medium and short term landslides, and can directly or indirectly reflect the general tendency of landslide deformation. The displacement characteristics and development of five landslides in Qingjiang bank are analyzed The trend provides a scientific basis for reservoir water storage and reservoir area immigrants and local government disaster prevention decision-making.
