求解了无拉力双参数地基上厚、薄板受任意移动荷载作用下的动力响应问题和板的脱离问题。从板-地基接触系统的分区广义势能泛函出发，通过建立和分析板单元区、地基单元区和连接板-地基的接触单元区的势能泛函，给出求解无拉力双参数地基板受任意移动荷载作用下的动力响应问题的分区广义协调元法。利用纽马克（Newmark）法经MATLAB编程叠代数值计算，验证了文中方法分析无拉力双参数地基板的动力响应问题是有效的。

Dynamic response problem about plate on tension-free double parameter foundation with moving load

A dynamic response problem about thick-thin plate on tension -free double parameter foundation with random moving loads and problem about plate untouched foundation have been solved. From the generalized potential energy functional analysis of subsea of system about plate-foundation touching beginning, we can get subsea generalized harmonious element about solving dynamic response problem of plate on tension-free double parameter foundation with random moving loads through building and analyzing potential energy functional analysis of section about plate element, section of foundation element and section of plate-foundation element. We use method of Newmark and programme with MATLAB through iterativeness and get dynamic response value of every point in midst plane about moving loads in different instantaneous, different place. We also get the region and area of plate untouched foundation. Through numerical calculation, we can verify the method proposed, with which analyzing dynamic response problem about thick-thin plate on tension-free double parameter foundation , is effective.
