摘　　要：采用有限条法和弹簧体系分析弹性支承结构的弯曲问题 通过弹簧模型分析 ,弹簧体系可以有效地模拟各种弹性支承体系 ,如文克尔弹性地基和双参数弹性地基 ,还可以模拟各种内支承和复杂边界条件 用线型弹簧模拟内支承 ,对连续板结构进行了数值分析并与经典解进行了比较 ,同时对弹性地基板进行了计算 数值结果表明 ,本文方法具有较好的精度 。A procedure incorporating the finite strip method with spring systems to treat plate structures on elastic supports is proposed.Through the analysis of spring system,different elastic support models,such as Winkler elastic foundation,two-parameter elastic foundation,can be modeled using the spring system,also the inner line or point elastic supports and complicate mixed boundary conditions can be simulated.A multi-span simply supported plate is investigated using the line elastic supports as interior supports and the results have been compared with the classic solution.Also the plate resting on elastic foundation is studied.Numerical result shows that this procedure has good accuracy and can be applied to many different types of elastic supported structures.
