THE EFFECT OF SOIL IMPROVEMENT ON FOUNDATION & SUPER STRUCTURE DESIGN

For a particular arrangement of superstructure, soil strength is the most important factor
affecting the design of its supporting raft and hence the cost of construction. Folding of raft
or folded plate foundations can be used to reduce the material consumption in a raft design.
The beneficial effects to foundation and superstructure design by the selective soil
improvement below a raft or folded plate foundation were studied in this paper with the help
of Winkler and continuum methods of soil modelling.
