摘要
通过对裂隙岩体中大量随机分布的结构面调查资料的统计分析,得出结构面分布的统计规律,运用随机模拟的方法,建立了裂隙岩体的三维结构面网络。通过三维结构面网络图像,在大量实际工程岩体破坏面特征调查的基础上,提出了三维结构面连通率的概念,并应用岩桥破坏机理,选取通过破坏面的结构面,采用三维曲面拟合的方法,建立了三维结构面连通率的计算方法。
Based on statistics of randomly distributed joints in rock mass, the expectations and the associated degree of confidence of joint geometry can be obtained. Then, the three dimensional map of fissured rock mass can be simulated by Monte-Carlo method. Based on investigation on the failure surface property of many projects, 3D joint persistence of rock mass is defined. By using the rock-bridge failure theory and three dimensional surface approximating method, the persistence can be easily calculated.
