ROCK MECHANICS FOR DAM FOUNDATIONS

The most recent advances in the knowledge of physical properties of rock are summarized. The rock mechanics of dams is approached through an examination of the means used by engineers to design modern dams. The research required, and the interpretation of results of tests and measurements are reviewed. A discussion of the physical properties of rock covers such aspects as deformation in-situ under stress, shear strength determinations, methods of testing rock, and the classification of rock. The problem of water pressure in rock faults and joints and in rock fissures is discussed. This covers the aspects of drainage versus grouting, and practical examples of rock drainage (arch dams). Attempts to calculate rock abutments (mainly for arch dams) are outlined. Typical examples are described of modern dams with different foundations on rock. These include the Malpasset dam, dams with reinforcement of rock foundations, buttress dams with foundation reinforcement, and dams with other foundation problems. The present trend in rock mechanics and concrete dam foundations is summarized.
