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 model experiment has been carried out to study the problem of the broken rock falling from the slope into the river. It is possible to build the dam by the loose blasting and the landslide effect. When the friction coefficient f of the hill is small, Distance; while f is larger, the farthest distance of slippage decreases. There are two possible critical angles for the natural sliding of the bulk: one from the standstill to the beginning and the other from the standpoint of motion to stop. Experiments also show that it is effective to increase the minimum resistance of the first row of blasting in order to increase the furthest distance of the stack and the heap height of the river core.
