摘要
针对上覆岩体结构的复杂性,将节理、裂隙及正交各向异性岩体视为损伤岩体,建立了裂隙损伤岩体三维动态有限元分析模型,给出了较详细的三维仿真模拟有限元实施格式,完成了可考虑多种工程因素且能在WINDOWS下运行的三维模拟软件。分析模拟结果显示,对岩体结构复杂性的处理方式是可行的,所研制软件是有效的。
In light of the complexity of rock mass structure in mining area, joints, cracks and anisotropic rock masses are regarded as damage rock mass in the paper. And a three dimensional (3D) damage model of finite element analysis is set up for joint-crack rock masses. Concrete formulas of 3D finite element imitation are given in greater detail. The 3D simulating software is completed, which can be carried out in WINDOWS. All kinds of engineering factors can be considered in the software. Case analysis results show that the given way is feasible to deal with complex structure rock masses and the developed software is effective.
