.... On one hand the Quantile Monte Carlo (QMC) simulation is used to determine the optimal design variables (i.e., the thickness of two liners). On the other hand, the well-known Kriging metamodeling technique is undertaken to approximate the limit state function in the augmented reliability space (i.e...

Based on allometric growth of mining overburden separated strata, which would provide a new research and analysis method for control and prevention of mining subsidence damage, we establish the model of mining subsidence. metals & mining Thickness surface subsidence...

... lamination can cause size effect even without considering size effect of the intact rock and rock joints. The influence of lamination orientation on size effect is distinct and is orientation-dependent while the influence of lamination thickness is minimal. Changing dip or stress direction will affect...

... and numerical models. In the tested models beddings dip varies from 0, to 90 degrees. Layer thickness is considered 16 millimeters. The tunnel width and height are considered 10, 12, and 14 times as big as the bedding thickness. Also the joint spacing is one to two times as big as the bedding thickness. Due...
