Abstract
The analysis of design and operation experience of grain elevators is executed. Metal silos of high capacity are representatives of structures with continuous foundations that perceive increased and multiple loads. Methods of regulating the stress-strain state with the help of creation of artificial bases are considered in detail. A technique for estimating the stress-strain state and calculating the deformations of continuous foundations is proposed.

The construction of railway transfer platforms for crops and other loose products and materials is a vital area. Such products are stored in silo-type elevators using high-capacity metal silo towers
Summary
The analysis of design and operation experience of grain elevators is executed. Metal silos of high capacity are representatives of structures with continuous foundations that perceive increased and multiple loads. The methods are divided into the following types: 1)rapidly increase mechanical strength and impermeability of soil; 2)provide stabilized soils with impermeability only; 3)increase water resistance and thickness of soil (dewater clayey soil and muck). In order to give impermeability to sandy soils, where we cannot use cement, it is replaced with silicate and clay-silicate solutions, which can provide impermeability for sandy soils with permeability index from 20 to 100 meters per day.
