Stability Analysis of Loess High Slope under Dynamic Compaction Based on Matrix Discrete Element Method

In order to investigate the safety and stability of loess high slope under dynamic ramming, MatDem software was used simulate process heavy rammer compacting spot which 11 m away from toe slope. The applied with different energies 10000 kN·m, 8000 6000 kN·m. this way, action tamping can be determined. results show that presented circular landslide damage by compaction. Under same ramming times, decrease energy, degree gradually reduced. According displacement value monitoring points, large horizontal vertical points in were obtained. When energy kN·m maximum displacements 15.45 10.72 m, 17.43 11.91 m. soil at bottom would produce slight vibration. Considering actual project, when minimum safe distance recommended 25 20 KN·m, remained stable as a whole, suggested should not less than A collapse compaction determined, provided strong guidance for construction
