【摘要】 软粘土地基变形的重要特性之一,是其具有粘滞性。由于粘滞性的存在,土体在固结过程中变形呈现出次时间效应。同时,天然地基有成层性的特点。在建立了一个成层软粘土地基模型的基础上,提出了求解变荷载下成层软粘土一维固结问题的半解析方法,编制了相应的计算程序。通过在单层情况下与已有的解析解的比较,证明半解析方法的正确性和有效性。最后给出一个算例,得到了有关的固结曲线,揭示了成层软粘土地基的固结特性。更多还原

【Abstract】 Viscosity is one of the important characters of soft clay. Due to the viscous deformation of subsoil,consolidation shows secondary time effects. Another important character of natural subsoil is layer. According to a layered soil model,the semi-analytical solution for one-dimensional consolidation of layered soft clay under time-dependent loading is presented and the computer program is developed. Based on the computing result,some useful consolidation diagrams are obtained and the relevant characters of the consolidation of layered soft clay is discussed.更多还原
