Abstract

Methods are described that make it possible to predict the size of compacted soil zones formed in the inter-pile space of a single-row pile foundation when a trench is stamped into it under a grillage. The solutions are based on the use of equations for the conservation of soil mass in a compacted area when a trench is stamped into it and a rigid material is stamped into the bottom of the trench. Different variants of possible forms of a compacted soil zone and a compacted expansion in the lower part of the trench are considered. The thickness of the compacted zone of the inter-pile soil is determined taking into account its density, the size of the stamped trench and the volume of rigid material stamped into the bottom of the trench. Based on the formulas obtained, comparative calculations were carried out, which showed that their results are quite acceptable. The methods are recommended for use in engineering practice after their experimental verification.
