In the proposed article the author examines issues determining physical and mechanical soils with organic matter content. Conditional definitions of organic soils depending on the value of the relative organic content matter are determined. The biogenic soils are examined using three groups - peat, blocked soils and sapropels. Depending on the relative content of organic substances, the author compares various peat types. The division of the soils with organic content is presented. A definition of sapropels is presented. The problem of complexity of determination of the amount of organic substances by calcination of samples is described. The current methods used to determine the amount of organic substances currently in Russia isexamined. The paper reviews physical and mechanical properties of organic soils. The on-site test-plate data is compared with laboratory test data. The problems of sapropel tests are described. The results of experimental studies, conducted at a construction site in the new suburban district of Moscow are shown. |
