摘要: 岩体结构面三维网络的计算机模拟,是近代计算机技术在岩石力学领域应用的一个重要方面。从现场观测得到的结构面数据只具有一维或二维的分布特征,而且通常包含采样误差。所以必须经过处理,消除采样误差后,才能用体视学的方法推求三维结构面的分布参数。岩体结构面三维网络的数据是根据三维结构面的分布参数,通过蒙特卡罗法抽样生成的。而结构面三维网络的图形显示可用Visual C++结合OpenGL技术实现。因而归纳了最新的对结构面参数测量误差校正的研究成果,并通过一工程实例说明了岩体结构面三维网络模拟的实现步骤。Abstract: Compute modeling for 3D-fracture network of hock mass is an important application of modem computer technique in nxk mechanics. Field data of rock fractures gotten in holes or on outcrops only possess 1D or 2D distribution characters, and often contain sampling error.So many kinds of corrections must be made before the data being used to determine distribution parameters of 3D-fracture with stereology. The source data of 3D-fracture network are devel-oiled from distribution parameters of 3D-fracture with Monte Carlo Method, and the visual display of the network can be implemented using Visual C++combined with Open GL technique. The up-to-date research of correction meth-ods for measuring data of hock fracture is reviewed in this paper, and the implementation of a 3D-fracture model for a practical project is displayed in order to illustrate the press of 3D-fracture network modeling.
