Forecasting model of safe thickness for roof of karst cave tunnel based on support vector machines
Kaiyun Liu · Rock and Soil Mechanics · 2006
Taking some tunnel as the background.and by using FEM numerical simulation,the factors affecting the safe thickness of roof of karst cave are analysed;and forecasting model of safe thickness of roof is obtained by support vector machines(SVM) and stepwise regression analysis.The result of calculation indicates that,SVM forecasting model not only has the advantages of convenience and swiftness compared with the linear regression model,but also has higher precision of prediction.
