Highly Compacted and Reinforced Soil Beds as an Efficient Method to Build Artificial Foundation Based on Weak Soils

Abstract

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.

Modeling of Hydrophysical Properties of the Soil as Capillary-Porous Media and Improvement of Mualem-Van Genuchten Method as a Part of Foundation Arrangement Research

“…The system of hydrophysical functions, which are proposed here, makes it possible to improve the accuracy of calculating the dynamics of soil moisture [16] and evaluation of irrigation rates [17], as well as predictions of crop yields [18][19][20][21][22]. These data are particularly important for planning the complicated foundations on weak soils [23], at the predesign-research part of the foundation arrangement researches. Such researches must be held before the completing of the drainage works [24].…”

Empirical-Statical-Dynamical (ESD) Methodology for Extrapolation of Rock Mass Properties for Construction of Tunnels

“…This had significantly stimulated the development of rock mechanics and tunneling as scientific and technical discipline as well as the wider application of research results into practice. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] investigations. So, it is necessary to find a way to extrapolate the necessary parameters from smaller volume of testing zone to the whole volume of the rock mass along the tunnel length.…”
