Numerical modeling of the failure process of the heterogeneous karst rock mass using the DDA–SPH method

Numerical modeling of the failure process of the heterogeneous karst rock mass using the DDA–SPH method

The sanding process caused by karstification in dolomite creates a special sandy dolomite stratum, where the frequent catastrophic instability of the surrounding rock occurred during tunnel construction. In this study, the micro-origin and macro-performance of the sandy dolomite stratum are first di...
