Suggestion of advanced regression model on friction angle of fault gouge in South Korea
Although friction characteristics of fault gouge are important to understand reactivation of fault, behavior of earthquake, and mechanism of slope failure, analysis results of fault gouge have low accuracy mostly than those of soils or rocks due to its high heterogeneity and low strength. Therefore, to improve the accuracy of analysis results, we conducted simple regression analysis and structural equation model analysis and selected major influential factors of friction characteristics among many factors, and then we deduced advanced regression model with the highest coefficient of determination (R2) via multiple regression analysis. Whereas most coefficients of determination in simple regression analysis are below 0.3–0.4, coefficient of determination in multiple regression analysis is remarkably large as 0.657.
