This is the third volume of a handbook which covers the whole field of soil mechanics, discussing deterministic and stochastic theories and methods, and showing how they can be used in conjunction with one another. The first volume discusses soil physics, while the second deals with the determination of physical characteristics of the soil. Australian Mining wrote of the Handbook ``a valuable addition to the extensive literature on the topic and will be found to be more useful than most.'' The main objective of the third volume is to present solutions to the problems of engineering practice. It deals with the most important theoretical and practical problems of soil mechanics, discussing the following in detail: stability of earthworks, load-bearing capacity and settlement of shallow foundations, design of pile foundations, soil mechanics in road construction, improving the physical properties of soils, the characteristics of soil dynamics, foundations for machines and soil behaviour as affected by earthquakes. The book not only presents up-to-date deterministic methods, but also discusses solutions of probability theory in the fields of design and safety.
