摘要
将直接顶视为可变形体， 根据支架围岩关系的整体力学模型， 从能量角度出发， 证明了支架工作阻力与顶板下沉量存在类双曲线关系， 并进一步探讨了直接顶高度、直接顶坚硬程度或损伤程度对此类双曲线关系的影响， 其结果对现场支护设计有重要的指导意义。
According to the global m echanical m odel of support resistance, im m ediate roof subsidence and surrounding rocks, the im m ediate roofis considered as a deform able body, and the hyperbolicrelation is the- oretically proved from pointview ofenergy. The effectofthe height, the elastic m odulus and the dam age de- gree ofthe im m ediate roofon the hyperbolic relation is further discussed. The results are ofsignificance to engineering supportdesign.
