摘要
通过对固体充填液压支架与围岩作用关系和支架与直接顶的二维力学分析,找出支架顶梁各支撑点的受力情况:(1)由于前、后顶梁的铰接点靠近中间一排立柱,铰接点对前顶梁的作用力方向为向上;(2)前排立柱受力FA是中间一排立柱受力FB的4.1倍,后排立柱受力FD是中间一排立柱受力FB的4.6倍。
By both the relationship between the solid back- filling roof support and surrounding rock and the 2- D mechanics analysis of roof support and immediate roof , find out the support force of the top beam each strong point：because the hinge point before and after the beam near the middle of a row of columns on the front top beam hinge point force in the direction of the upward; the front column force FA is 4.1 times the middle row column force FB, rear column force FD is 4.6 times the middle row column force FB.
