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...
