摘　　要：EFGM作为一种新的数值计算方法 ,具有只需节点信息而无须单元的特性 ,故在解固结方程方面有很大的优势。在计算分析中 ,此法容易构造固结方程的EFGM刚度矩阵和处理不同边界条件。对单面排水等条件的计算结果表明 ,EFGM在解决固结变形问题上 ,精度较高 ,处理边界准确。As a new numerical method, element free Galerkin method (EFGM) has more advantage in the solution to consolidation equation as it only needs the information of nodes rather than element. By this method, it is easy to construct the EFGM matrix formulation of consolidation equations and to deal with different boundary conditions in calculation and analysis. The results of calculating the condiditions like single drainage have shown that in the deformation of consolidation, EFGM is more accurate in calculation and the treatment of boundary
