以温福铁路分水岭隧道为例，介绍水压爆破技术特点。体现了水压爆破既能有效地控制爆破震动，又可防毒降烟。同时破碎围岩较均匀、大块率降低，有利于机械化施工，显著提高了经济效益。

Taking Fenshuiling tunnel on WenzhouFuzhou railway as project case, the author presents the features of hydraulic 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.
