摘　　要：利用岩体损伤分析原理,通过裂隙率观测,找出了岩体损伤参量与裂隙率之间的关系,建立了岩体与岩块弹性模量之间的修正关系式,结合位移反分析原理得出芦岭矿810采区围岩岩体有效物理力学参数的修正值。This paper found out the relation between breaking parameters and cracked frequency of rock body one the analytical principle of rock body breakage and through observation of cracked frequency,set up a correction relation between rock body and its elastic modulus,and obtained an effective correction value of physico-mechanical parameters of surrounding rock in No.810 mining district of Luling Mine on the counter-analytical principle of rock displacement.

关 键 词：围岩 损伤分析 裂隙率 物理力学参数 修正
