A New Landslide Forecast Method and its Application in an Opencast Coal Mine
In order to find the controlling factors of slope stability and instability criterion for slope engineering, and provide a theoretical basis for developing landslide control technique, the regression function and regression parameter were obtained by applying the generalized least square method, and the partial linear model was derived after the regression analysis for the slope horizontal displacement and monitoring time by using B-spline method. The front several terms of the Taylor’s series were intercepted after the function of the partial linear model was expressed as Taylor’s series expansion. The cusp catastrophic model was eventually obtained by means of variable substitution, and the risk of landslide would be recognized with the aid of the catastrophic criterion. The method of landslide forecast was verified by the field monitoring data.
