Investigation of compacted sandy soils properties at base of buildings and structures

Abstract

Based on the data of physical and mechanical properties of soils obtained at various construction sites in Moscow, the article discusses in detail the issues of soil compaction and determination of bearing capacity. The article describes various methods of soil compaction, which must be taken into account to determine the value of the physical and mechanical characteristics of the soils laid down in the project. It is especially important at the initial stage to determine the necessary parameters of the compacted base. The described dependences of the deformation modulus and the compaction coefficient for the artificial base were carried out in comparison with engineering and geological data obtained from real objects in the city of Moscow. The analysis of the results obtained for sands with different granulometric composition was carried out and graphs of the dependencies of the data obtained were constructed. The article also describes the controlled parameters when using a compacted sand cushion as an artificial base.
