STABILITY OF EARTH AND ROCKFILL DAMS DURING EARTHQUAKES

The current state of knowledge related to earthquake-resistant design of earth dams is reviewed and illustrated. The cases of the Hebgen Dam (1959) and the Lower San Fernando Dam (1971) are discussed, and possible ways in which an earthquake may cause failure of an earth dam are examined. Past practice in the evaluation of slope stability during earthquakes is reviewed. In a discussion of the selection of seismic coefficient in pseudo-static analysis, consideration is given to the use of empirical values, rigid-body response analyses, visco-elastic response analyses, comparison of methods for determining seismic coefficients, and the limitations of pseudo-static methods of evaluating slope stability. Dynamic response analyses are reviewed. Details are given of the analysis of the Sheffield Dam failure. Design precautions to preclude major earth dam failure are listed. The insufficiency is noted of well documented case-histories which could provide a basis for quantitative evaluations. Considerable progress has, however, been made in new design concepts for earthquake-resistant embankments, methods of analysis of dynamic response of embankments and testing for soil behavior during earthquakes.
