Soil mechanics studies the behavior and attributes of soil. The subject of soil mechanics helps in developing an understanding of buildings or structures that are supported by soil. The strength of the soil can be measured by the friction and aggregation found in it. It plays a crucial role in geotechnical engineering. For all those who are interested in soil mechanics, this book can prove to be an essential guide. Constant effort has been made to make the understanding of the concepts of soil mechanics as easy and informative as possible, for the readers.
