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
