摘要/Abstract

摘要： 根据双层地基固结理论,推导出瞬时加载、单面排水、初始孔压非均布的一维固结解答。给出了双层地基不同工况对应的简化初始孔压分布图,以便实际运用。通过编制的计算程序,分析了不同初始孔压分布对双层地基一维固结性状的影响。结合硬壳层地基固结的计算实例,分析了硬壳层应力扩散效应对固结曲线影响。

Abstract: According to the consolidation theory of double-layered ground, a solution is given to the problem of one-dimensional consolidation in consideration of instant load, singleside drain and non-uniform distribution of initial pore water pressure. The simplified diagram of initial pore water pressure distribution under different working conditions is given for engineering practice. The influence of initial pore water pressure distribution on one-dimensional consolidation behavior of double-layered ground is analyzed through computer program. The impact of stress spreading in dry crust on the consolidation curves is illustrated by calculating examples.

Key words: :distribution of initial pore water pressure, hybrid method, double-layered ground, one-dimensional consolidation, stress spreading, dry crust
