摘要
本文论述了高陡路堑爆破开挖中减振技术,通过采用预裂深孔松动控制爆破技术、同段位高段别微差起爆技术,实现了降低爆破震动、控制高程振动放大效应、减轻累积爆破损伤作用,减轻了爆破震动带来的边坡破坏扰动作用,保证了高陡边坡的长期稳定。
The paper relate and analyze decreasing vibration technology of blasting excavation in rock cut of high and steep slope, through adopting pre-shearing loose blasting technology of deep hole and millisecond order detonation technology, it should reduce blasting vibration, control elevation amplification effect of vibration, and alleviate Cumulative damage effect, so as to ease disturbance effect to rock slope and ensure the long-term stability of the high and steep slope.
