| Abstract: | Taking Fenshuiling tunnel on Wenzhou-Fuzhou railway as project case, the author presents the features of hy- draulic blasting technology. It is demonstrated that, due to the application of the hydraulic blasting technology, the blasting vibration can be effectively controlled, the blasting fumes and dusts can be effectively reduced, uniform muck blocks can be produced and the ratio of large muck blocks can be minimized. It is concluded that hydraulic blasting technology is helpful to mechanized construction and helpful to the improving of the economic efficiency. |
