A controlled blasting demolition of three landscape rooms with turriform frame construction in complicated environment was introduced. For the turriform (hexagonal) frame construction with high stability, the ratio of height to width is too small to collapse. It focused on the burst attitude of the frame on symmetric axis in collapse direction. Through blasting plan and the pre-treatment measures, the proper blasting parameters and cut heights were determined. By adopting safe protection measures, the three constructers collapsed in different directions and times, vibration was reduced, and th...
