Book Description

Combining principles of Newtonian mechanics and Terzaghian soil mechanics with principles of earth sciences, thermodynamics, physical sciences and wave mechanics, the author and his team have devised a road map for a logical approach to soil as particulate matter in modern geotechnical engineering. This manual explains the analysis and design aspects of a range of DDS columns and discusses the resolution of foundation problems in so-called treacherous expansive soil deposits by the development of cohesive non-swelling soil technology. This manual will assist consulting engineers in designing DDS systems, enabling contractors to provide competitive bidding and aid in teaching the subject with greater clarity.
