... microscale features similar to RVEs, and provide a more economical solution approach than those methods that explicitly model all microcracks in rock. To create a random field for macroscopic fracture strength field, we first generate several realizations of rock with a prescribed crack density...

..., are inappropriate to analyze this issue at the meso/microscopic scale. In this study, using the experimental pore size distribution curve, the morphological aspect of porous network is represented by the excursion of Gaussian Random Field. Essentially, the extraction of accessible pores for a given gas pressure...

... methods. Statistical distributions describing the factor of safety (FS) of a trial slope are generated. For reference, purely random Gaussian fields with increasing variance are examined first. Kriging and other spatial interpolation methods are then introduced using subdomains of the random field...

... ABSTRACT: Presence of weak spots or weak planes at critical locations could be lead to failure of a slope or a tunnel project. A systematic way of dealing with spatial variability of soil and rock using random field model is introduced and used to characterize the properties of a weak...
