This paper mainly carried out analytical theory for consolidation and its engineering performance of double-layered composite ground with granular columns considering smear effects and stress concentration effects,and discussed possible variational laws considering different cases,also with the common applicability of this analytical theory.
研究了考虑涂抹效应和应力集中效应的双层散体材料桩复合地基固结解析解及其工程应用,分不同情况讨论了特征根的可能变化规律,也讨论了解析解转化为双层竖井地基以及双层天然地基的普遍适用性。
Based on the equivalent consolidation degree,the method that considers the smear effects diminishing the permeability of the clay in the smear zone,which can be transformed into the reduction on horizontal permeability coefficient of the soil in the efficient zone,is presented.
按照固结度等效的原则,提出将单井涂抹效应对涂抹区内土体渗透性的弱化作用转化为减小单井影响区内土体水平向渗透系数的方法,并讨论单元尺寸对固结度的影响。
