Experimental study of crack propagation and failure around a horseshoe tunnel during nearby blasting

To investigate the effects of nearby blasting on a horseshoe tunnel and to analyze dynamic response and crack growth with different loading directions, five laboratory experiments were performed using granite specimens of a rectangle plate containing a blast hole and horseshoe tunnel structure. HS p...
