摘要： 采用Laplace变换及Hankel变换研究弹性圆板在饱和地基上的固结位移．在Laplace变换域上建立了求解弹性圆板固结位移的第二类Fredholm积分方程，由数值反变换获得时域解，给出了对工程实践有参考价值的计算结果．计算结果表明，弹性板的固结位移随饱和土的排水泊松比的减少而增加，而弹性板的初始位移随饱和土的不排水泊松比的减少而增加．
关键词： 饱和半空间;  弹性圆板;  固结位移    
Abstract: The paper studied the consolidation displacement of an elastic circular plate on a poroe-lastic foundation by Laplace transform and Hankel transform．The Fredholm integral equation of the second kind is established in the Laplace transform domain in order to obtain the consolidation displacement of the elastic plate．Laplace transform solutions are converted to time domain solutions by numerical methods．The numerical results useful to engineering practice are given．The results obtained indicate that the consolidation displacement of elastic plate increases with decreasing drained Poisson’S ratio，and the initial displacement of elastic plate increases with decreasing undrained Poisson’s ratio．
Key words: poroelastic half space    consolidation displacement    elastic circular plate
