摘　　要：根据Reissner中厚板理论和胡海昌的简化计算方法,寻求能满足全部自由边界条件的试函数构造2个广义位移,利用伽辽金法并结合数值算例探讨了双参数弹性地基上四边自由中厚板的受力特性,文中方法简便适用,克服了有限单元冗长计算的缺点,其计算精度完全可以满足工程实际的需要。Approximate solutiongs for the bending of moderately thick rectangular plates on two-parameter elastic foundations as described by Reissner＇ s theory are presented, with functions which satisfied all free boundary conditions form two generalized displacement, A Semi-Analytical Numerical Method was put forward to solve the Foundation Shear Module Influence with Moderate Thick Plate. Projects will benefit notably from the consideration of the transverse continuity of the foundation, which will amend the valuess of the plate＇s deflection and bending moment. The results agreeed well with With the accurate answers, and its is more simple than finite element method.
