摘要
通过运用现有多层地基一维固给解析解和迭代法，建立了能考虑上体自重的非线性一维大应变固结问题的半解析方法，编制了计算程序，然后通过详细的计算，得到了有关孔压和沉降曲线，讨论了在各种因素影响下地基的孔压消散、沉降以及固结度的发展情况，揭示了大应变固结性状的复杂性以及在通常情况下考虑全体自重和大应变效应的必要性。
Based on the general analytical soution available for the problem of one-dimensional consolidation of layered soils and ite-rative methods, the semi-analytical solution for one-dimensional non-linear large-strain consolidation considering the selfweight of soils is presented with computer program developed. According to the compotational results, some useful oonsolida-tion and setilement diagrams are prepared and the influences of various factors on the dissipotion of pore pressure, the settle-ment and the degree of consolidation are compared and discussed. The results demonstrate that the behavior of one-dimension al nonliner large-strain consoidation considering the self-weight of soils is very complicated and in peral the effect of the selfweight of soils and large strain cannot be ignored.
