Experimental studies of a weak clay base reinforced with sand piles

Abstract

The study was aimed at assessing the deformability of a weak water-saturated clay base reinforced with a group of sand piles in the form of a continuous pile field,when they are jointly deformed under load. Existing studies consider the interaction of free-standing soil piles with the surrounding soil,methods for their calculation,without taking into account the joint operation of a group of piles in a deformable soil massif. The main research results were obtained in the form of new experimental data on the operation of a group of sand piles during their joint deformation with weak water-saturated clay soil massif under a stamp. The significance of the results obtained for the construction industry lies in the fact that the experimental data presented can be used in further theoretical studies to develop a calculation model that allows taking into account the peculiarities of the interaction of sand piles in a pile field with each other and with the surrounding soil massif and are of practical value.
