APPLICATION STUDY ON STABILITY ANALYSIS AND TREATMENT WITH BLAST-UNLOADING FOR LANDSLIDE
爆破卸载治理滑坡及稳定分析的应用研究

The directional blasting is implemented for unstable landslide to toss soil from the top to the toe to lower the gravity center of the landslide. The Sweden circle method is adopted for the stability analysis of landslide,and the chamber charge,blasting acting index and the minimum holdout line are designed and calculated. The equilibrium method of physical volume is used to estimate the heap outline after blasting,and the stability of the landslide is analyzed again. Special measures are taken to weaken blasting vibration and the blasting control purpose is achieved.
