摘要
利用数值流形方法可以方便有效地统一处理连续和非连续变形分析的优点,借鉴Goodman单元的相关理论,提出一种基于数值流形方法的模拟节理、裂隙和软弱夹层等岩体结构面的新方法,极大简化了含岩体结构面的复杂岩体工程的前处理及分析过程.算例分析表明了该方法的正确性和有效性.
The numerical manifold method(NMM)provides a uniform framework for analyzing both continuum and discontinuum.Incorporating the advantages of the NMM formulations and the well known Goodman element,a novel method for modeling the rock discontinuities is developed.The method which is particularly suitable for modelling joint or weak layer in rock,is proved to greatly simplify the preprocessing and analysis of the jointed rock mass,as a result,it is generally applicable for rock mechanics and rock engineering.Several test examples illustrate the correctness and effectiveness of the proposed method.
