为了形成统一的计算机程序去处理各类岩石力学问题,本文根据两类位势层的物理意义,阐明了各类边界元间接法在形式上的一致性与原理上的共同性。不同性质的点源引起不同特征的基本解,由此区别不同方法。根据上述原理形成的源程序可以同时处理无限平面问题,复合平面问题、半平面问题、非均质问题(包括各种节理单元)及粘弹性问题等。给出了几个矿山应用实例。本文的原理适用于复杂材料模型,如材料非线性及各向异性介质等。
In order to form a unified computer program to deal with all kinds of rock mechanics problems, this paper, based on the physical meaning of the two types of potential layers, clarified the consistency of the various types of boundary element indirect methods in terms of form and common in principle. Point sources of different natures cause fundamental solutions of different features, thereby distinguishing different methods. The source program formed according to the above principle can simultaneously deal with infinite plane problems, composite plane problems, half-plane problems, heterogeneous problems (including various joint elements), and viscoelastic problems. Several mine application examples are given. The principles of this paper apply to complex material models such as material nonlinearity and anisotropic media.
