摘要
探讨了露天矿边坡侧压力及应力的来源,指出了地应力产生的主要原因在于重力。重力作用既产生竖向地应力,和水平地应力。给出了重力所致水平地应力的科学表达方式。提出了露天矿边坡侧压力及水平地应力计算的新方法,找出了露天矿边坡水平地应力的竖向分布规律。
The author probes into the source of lateral pressure and stress of the slope in opencast mining.that the primary reasons for caused the crustal stress is the gravity has been pointed out in this paper.The gravity not only can caused the vertical crustal stress,but also it can caused the horizontal crustal stress.It gives the scientific voice way of horizontal crustal stress by gravity.A new method to calculate the lateral pressure and horizontal crustal stress of the slope in opencast mining has been given.The vertical dispersive law of horizontal crustal stress of the slope in opencast mining has been discovered.
