摘　　要：块体理论把节理长度假定为无限长，而实际工程中揭露的节理 迹线长度是有限的。因此，用块体理论对岩体稳定性所作的分析结果将产 生较大误差。本文把节理迹线无限长的假定修正为有限长，并首次将节理 随机概率模型引入块体理论，为使这一理论更趋完善作了新的尝试。Block theory regards joint length as nolimited length,but actual trace length is limited, therefore, analysis of block theory yields a lot of errors. This article modifies joint trace length from nolimited to limited,and introducts joint probablitic model to block theory for the first time. The Aim of the Authors is to make block theory analysis more accurate,and make a mew test to modify block theory.
