| 摘 要： | 在分析饱和软土地基不同排水固结处理方法的基础上,将饱和软土渗透固结按其作用机理的不同区分为压缩型固结和渗透力型固结;渗透力型固结又分为减压型和加压型两种形式,将真空预压归类于减压型渗透力固结。提出了超稳定渗流孔隙水压力的概念,得出了渗透力型固结的过程就是超稳定渗流孔隙水压力逐渐转化为有效应力的过程的结论;建立了渗透力型固结沉降计算的简化方法。并对渗透固结处理软土地基的若干问题进行了分析和讨论。

| Abstract: | Seepage consolidation of saturated soft soil is divided into two types: compacted consolidation and seepage force consolidation,according to their different mechanism on the basis of analyzing different drained consolidation treatment methods for saturated soft soil foundation.And the seepage force consolidation is then divided into two subgroups: the decrease pressure and the increase pressure,and the vacuum method of preloading belongs to the type of decrease pressure.A new concept of pore water pressure ... |
