This paper presents the variations of void ratios

compression coefficients

compression index and compression modulus of Xiamen muck with consolidated pressure at beginning. The second section describes the laws of coefficient of consolidation variation with pressure or void ratio. At last

it is discussed that the pressure secondary consolidation deformation develops with time at a given constant temperature and pressure. The ratio of secondary consolidation deformation to primary’s one

and quantitative relations between secondary consolidation deformation and pressure are described.
