Abstract

Very little technical information is available in literature about the compressibility characteristics of peat and organic soils. The problem of estimating consolidation settlements is even more complex for moderately organic hetrogeneous soils, such as mixtures of organic and inorganic soils.

Two known factors affecting compressibility characteristics of organic soils are: natural moisture content and consolidation pressure. From several sites, natural moisture content and compressibility data was collected for organic soils. The data is presented graphically for low and moderate consolidation pressures.

On the basis of the above mentioned data, coefficient of compression index for a moderately organic deposit was estimated. At this site, field consolidation was accomplished by surcharge loading method. Presented are the estimated and observed values of consolidation settlements. For the case history studied, approximately 50 percent of settlement occurred during the first few days.

Field Consolidation of a Moderately Organic Hetrogeneous Deposit

Very little technical information is available in literature about the compressibility characteristics of peat and organic soils. The problem of estimating consolidation settlements is even more complex for moderately organic hetrogeneous soils, such as mixtures of organic and inorganic soils.

Two known factors affecting compressibility characteristics of organic soils are: natural moisture content and consolidation pressure. From several sites, natural moisture content and compressibility data was collected for organic soils. The data is presented graphically for low and moderate consolidation pressures.

On the basis of the above mentioned data, coefficient of compression index for a moderately organic deposit was estimated. At this site, field consolidation was accomplished by surcharge loading method. Presented are the estimated and observed values of consolidation settlements.
