In this study, three-dimensional simulations of cone penetration tests (CPT) in cemented sandstone have been investigated using the Discrete Element Method (DEM). We generated realistic grain size distribution numerical Ustyurt-Buzachi Sedimentary Basin samples. Numbers CPT at different bond strength values were performed with penetrometer vertically moved down a constant rate. The results real...

Abstract. Construction of cavities in the subsurface is always accompanied by excavation damage. Especially context deep geological nuclear waste disposal, evolving damaged zone (EDZ) near field emplacement tunnels utmost importance concerning safety aspects. As EDZ differs from intact host rock due to enhanced hydraulic transmissivity and altered geomechanical behavior, reasonable location-dep...
