x PREFACE
10. The sequence of topics and subtopics is sought to ~ made as logical as possible.
Symbols and Nomenclature adopted are such that they are consistent (without sig-
nificant variation from Chapter to Chapter), while being in close agreement with the
intemational1y standardized ones. This would go a long way in minimising the possi-
ble confusion in the mind of the student.- The various theories, formulae, and schools of thought are given in the most logical
sequence, laying greater emphasis on those that are most commonly used, or are
more sound from a scientific point of view. - The author does not pretend to claim any originality for the material; however, he
does claim some degree of special effort in the style of presentation, in the degree of
lucidity sought to be imparted, and in his efforts to combine the good features of
previous books in the field. An sources are properly acknowledged.
The book has been designed as a Text-book to meet the needs of undergraduate curricula
ofIndian Universities in the two conventional courses-"Soil Mechanics" and "Foundation Engi-
neering". Since a text always includes a little more than what is required, a few topics marked
by asterisks may be omitted on first reading or by undergraduates depending on the needs ora
specific syllabus.
