摘要 空间节理长度只能通过岩石暴露面上节理迹线长度来量测,但是节理迹线是节理面与岩面交切的结果,迹长在多大程度上能代表节理真实长度是值得研究的.利用计算机模拟的方法和数学解分析了迹长与节理真实长度的统计关系.结果表明,不管是数学解还是模拟解,迹长与节理长度比值的概率密度分布具有相同的分布形式,均描绘出岩面上大迹长出现的机会大(具有高概(频)率密度),小迹长出现的机会小(具有低概(频)率密度) Joint size is determined by measuring joint trace length on a outcrop, but the joint trace is an intersection line of joint surface and rock face,thus it is worth studying that to what extent the joint trace length can represent joint size. The statistical relationship between joint size and trace length is analysied by computer simulation and mathematical solution. The result shows that probability density distribution of the ratio of the joint size and trace length has identical distributed form for both simulated solution and mathematical solution, which indicates that big trace length on rock face has much opportunity of appearing (having high probability/frequency density) and little trace length has few opportunity of appearing (having low probability/frequency density).
