| A 5¡12m thick tideland has been created in front of a new sea-dyke due to the rapid sedimentation occurring for 22 years. It is confirmed from theoretical analysis and soil tests that the deposit is in under-consolidation state. An analysis shows that when the average sedimentation rate is over 1-5cm/year for a soil with $c_v$=0.0005-0.001$cm^2$/s, excess pore water pressure exists in the deposit. It is known that the lower sedimentation rate than average in the initial deposition stage results in lower dissipation of excess pore pressure and vice versa. It is emphasized that under-consolidation behavior should be taken account in settlement analysis because structures founded on such deposits give higher settlements. |
