| 摘 要： | 针对单层Gibson地基模型，研究了半透水边界饱和土层在各种荷载作用下有效应力以及固结度的变化．运用Laplace变换求得了频域内有效应力在任意荷载作用下的解，并结合数值Laplace逆变换，对几种常见荷载作用下的固结进行了讨论，通过具体算例研究了各土性参数对固结的影响．结果表明，半透水边界Gibson地基的一维固结与传统固结理论有一定的差异．

| Abstract: | Laplace transform was used to study the one-dimensional consolidation of saturated Gibson soils, assuming that the modulus of compressibility is linear with depth; and has semi-pervious boundaries under arbitrary loading. The general solution in the Laplace transform field can be obtained, and the effective stress in the soils under arbitrary loading can be calculated by Laplace inversion. A numerical example revealed some characteristics of elastic soils consolidation. It is shown that the consolidation of Gibson soils with semi-previous boundaries is different from that in Terzaghi's consolidation theory |
