滑坡概率在边坡稳定性分析中的应用
Probability of Landslide in the Application of Slope Stability Analysis
摘要
Abstract
By using logistic regression models and deterministic coefficient CF,we establish a landslide prob-ability forecasting model for slope stability analysis.Combined with 42 slope cases of ionic rare earth mine in Gan-nan,we select 5 influence factors as severe,cohesive force,internal friction angle,slope angle and pore pressure ratio as input,and slope state as output,regression analysis is done by SPSS software,and a credible landslide probability fitting function is got.We feedback the forecast model and analysis results to the sample data,sample data input value and predicted value difference under 10% of more than 95%,illustrates the rationality of the fore-casting model;Accurately predicting the nine rare earth mine slope stability shows the accuracy of the prediction model.The difference between the sample data input value and the forecast value below 10% is more than 95%, explained the rationality of the forecasting model.The stability of 9 rare earth mines is predicted and the accuracy of the prediction model is explained.关键词
