【摘要】 岩体中结构面的存在对岩体的力学特性有很大的影响,研究岩体的强度参数,必须弄清结构面在岩体中的分布情况,了解结构面对岩体强度的影响程度。大量的岩体工程实例表明:岩体的变形和破坏规律取决于岩体结构面的性质,岩体工程的稳定性状态受岩体自身结构控制。因此,为了保证岩体工程结构稳定和生产安全,必须加强对岩体结构面的研究,采取一定的方法和手段控制岩体结构面的变形和破坏。 本文以影响岩体工程稳定性的岩体结构面为主要研究对象,根据Monte-Carlo法原理,利用计算机可视化编程技术,采用VC和C语言程序编制了结构面网络模拟系统。 利用所开发出的网络模拟系统对某边坡工程的结构面进行模拟,对该边坡工程中节理裂隙分布进行计算机模拟,得出节理裂隙分布的结构面网络图、等密度图、玫瑰花走向图和RQD值图等。通过等效结构面网络模拟真实的岩体性质,从模拟结果与实际情况看,Monte-Carlo法网络模拟得到的各项结构面的参数与实际情况较为吻合,为进行结构面连通性、RQD值等岩石力学计算提供了较为真实的模型和数据。更多还原

【Abstract】 Existence of structural planes affect greatly rock mass of dynamical properties in the rock mass, Reasearch rock intensity parameters of rock mass must understand distribution regulation of structural planes in the rock mass,and structural planes to rock mass intensity influencial degree. Numerous examples of rock mass engineering indicate that the deformation and breaking law of rock mass depends on its structural characteristics , and the stability of rock mass construction is controlled by the very structure of rock mass. Therefore, in order to ensure the structural stability of rock mass and production safety, must strengthen researches of rock mass structural planes and take adequate measures for controlling the deformation and breaking of rock mass structural planes.This paper takes rock mass structural plane that influences the stability of rock mass construction as the main subject of investigation, According to Monte-Carle method principles, utilizing visual programming technology of computer, and taking and advantage of VC and C language program.to write the system of structural plane network simulation.Finally, utilizing this system going on simulate the structural planes of a slope projects,distribution of joint plane and crack going on computer simulation to this projects, and obtaining structural planes graph of distribution of joint and crack, equal density gragh, rose trend graph and RQD value graph etc. Through equal structural plane network simulation real rock mass characteristics, from simulation consequence and real situation drawing a conclution that simulation different parameters is equal to real present situation, and offering real model and data to going on calculation structural plane anastomosis and RQD value etc.更多还原
