| 摘 要： | 运用改进的无单元Galerkin（Improved Element Free Galerkin，IEFG）方法计算机场复合道面的位移和应力，分析不同的节点数量和影响域比例参数对计算结果的影响.结果表明：节点数在4 000以上、影响域比例参数取2.5~3.5时计算结果较好；IEFG方法比无单元Galerkin(Element Free Galerkin，EFG)方法的精度更高，计算速度更快.计算结果可为机场道面设计提供参考.

| Abstract: | The displacement and stress of composite airfield pavement are obtained using Improved Element Free Galerkin(IEFG) method, and the effect of different node number and proportion parameter of influence domain on calculation results is analyzed. The results show that, the calculation results are good when the number of nodes is more than 4 000 and the proportion parameter of influence domain is 2.5~3.5; the IEFG has higher calculation accuracy and efficiency than the Element Free Galerkin(EFG) method. The calculation results can be referenced when the airfield pavements are designed. |
