摘要
研究了双层软土地基一维非线性大应变固结问题,同时考虑了土体受沉积作用影响的自重分布以及渗透性在固结过程中的变化等因素。对此复杂问题,利用半解析法进行了求解。通过与已有的大应变固结解析解对比,检验了半解析法在大应变固结分析中的有效性。最后较为详细地分析了双层软土地基一维大应变固结性状,并与相应条件下的小应变固结作了比较。
One-dimensional nonlinear large strain consolidation of double-layered soft soils was studied, in which the distribution of deadweight along depth due to sedimentation and the influence of varying permeability etc. were considered. The problem was solved by using semi-analytical method; and through the comparison between which available analytical solution to large strain consolidation, it is proved to be valid. Finally, the behaviour of one-dimensional large strain consolidation of double-layered soils was analyzed in detail, and compared with corresponding small strain conditions.
