Determination Horizontal Cosolidation Coefficient of Soft Clay,

Abstract

This article is represented the determination of coefficient of rate of horizontal consolidation of soil belong to amQ2 formation distributed in Mekong delta in laboratory. Procedure for horizontal consolidation test with drainage radially inwards according to BS 1377: Part 6: 1990. This result showed that the horizotal coefficient(ch) is always larger than the vertical coefficient (cv) of consolidation of soil and the ratio of ch/cv is in the range of 1,46 to 35,68 for small pressure (before preconsolidation stress) and from 1,50 to 5,89 in normal consolidated state.
