The introduction to this useful book starts by discussing classifications of falls, slide and flows, going on to a brief history, mentioning important historical personalities and events, such as Collin, Hutton Gregory, Gothernburg harbour quay wall and Fort Peck dam failures and the roles of Terzaghi and Skempton.
Chapter 2, discussing natural slope failures, contains a notable series of drawings, photographs and analyses of various kinds of slides, including such classics as Herne Bay cliffs, South Wales valley landslides and the Black Venn mudslides.
Fundamental properties of soils and rocks are discussed in Chapter 3, where concepts of effective stress and of residual strength are introduced and the importance of discontinuities discussed. In Chapter 4, discussion on measurement of shear strength, ring shear testing is emphasized; other methods of testing are also discussed.
Principles of stability analysis (Chapter 5) begins with a consideration of the φ = 0 (total stress) method of analysis, although the author has previously (p. 71) mentioned the difficulties and limitations of this method; the bulk of the discussion is about various methods using effective stress parameters. The discussion continues in Chapter 6 where the use of computers, with detailed examples, and stability charts is discussed.
Detailed consideration is given in Chapter 7 to seepage and pore water pressures where examples are, among others, taken from Cow Green, Balderhead and Tarbela dams, as well as natural slopes at Herne Bay and the Isle of Sheppey. Chapter 8 concentrates on remedial measures, including ground anchors, drainage (both
