Highly compacted and reinforced soil beds as an efficient method to build artificial foundation based on weak soils

摘要

Reliable construction and maintenance of buildings and structures based on weak and highly-compressive soils are closely related to artificial methods of how to prepare for foundation works. And changing a layer of weak soil in deformed foundation with a compacted soil bed consisted of various strong materials (sand, gravel, pebble-gravel, slag, production waste materials and others) can be considered as one of efficient methods. With the existing calculation methods used the dimensions of compacted beds quite often appear to be overestimated, and this results in increase in costs and working hours needed to build artificial foundation. It is more rational to create highly compacted and reinforced soil beds. The article deals with the general outcomes of experimental and theoretical research on design and foundation works of these beds which give evidence of their efficiency and explicit possibilities to expand fields of application.
