摘要
本文用模型实验研究了被炸碎的岩石自山坡滑落进入河道的堆积问题,得到用松动爆破和滑坡效应进行定向爆破筑坝是可能的,当山坡摩擦系数f较小时,它对最远滑移距离有影响;而当f较大时,滑移的最远距离减少。散体自然滑落可能有二个临界角:一是它从静止到开始滑落的角度;另一个是它从运动到停止时的角度。实验还表明,为了增加堆积体的最远距离和河心堆积高度,增加第一排爆破的最小抵抗线是有效的。
In this paper, the problem of broken stones piled in river is studied by model experiments, those stones are brokened by explosion and slid from the hillside. The conclusion obtained is that it is passible to built a dam by directional blasting with the effects of flexible blasting and slid from the hillside.
