摘　　要：引入著名的邓肯—张模型,对平面应变下比奥固结问题进行了非线性数值分析,应用无网格伽辽金法推导出土体二维Biot固结的系统方程并编制了相应的无网格程序,最后通过一算例说明了该法的精确性和可行性。The famous Duncan-Zhang model is adopted to make nonlinear numerical analysis on Blot＇s consolidation problem. The system equation for 2D soil consolidation is given and the corresponding program is developed with element-free Galerkin method. The accuracy and feasibility of the EFG method for consolidation problem are verified by comparing the calculation results of a numerical example.
