摘要
无单元法可以求解复杂边界条件的边值问题，它只需结点信息而不需单元信息，故信息简单，特别适用于岩土工程数值分析。它的理论基础是滑动最小二乘法。本文对无单元法的基本理论作了阐述，并用算例说明了它的广泛应用前景。
Element free method is well adopted to boundary value problems with complex boundary conditions. By this method, only nodal data is required, and no element connectivity is needed. This method has been developed by the authors for geotechnique problems. Its basic theory is moving least squares method. In this paper, the fundamental theory and some numerical examples are presented.
