![]() Such approach uses implicit response functions according to the Response Surface Method (RSM). HDMR implements the inverse reliability analysis, meaning that the unknown design parameters are sought provided that prescribed reliability index values are attained. 2009 Chowdhury and Rao 2010) can be used to carry out the reliability index within complex rock-soil slopes when numerous random variables with high coefficient of variations are considered. ![]() High Dimensional Model Representation (HDMR) (Chowdhury et al. Thus, to calculate the slope safety factor in stability analyses two issues must be taken into account: 1) the uncertainties related to structural setting of the rock- slope mass and 2) the variability in mechanical properties of soils and rocks. These materials are characterized by a high variability in physical and mechanical properties. Stability analyses of complex rock-soil deposits shall be tackled considering the complex structure of discontinuities within rock mass and embedded soil layers. ![]() Kozubal, Janusz Pula, Wojciech Vessia, Giovanna HDMR methods to assess reliability in slope stability analyses
