COMPUTER MODELLING OF EMBANKMNT DAMS: RESPONSE TO EARTHQUAKE.

This article dealing with computer modeling for predicting embankment dam performance, concentrates on numerical solution methods and associated results. Seismic effects often constitute a major design hazard for a large dam and a realistic solution requires that the pre-earthquake static conditions be analysed, as well as the earthquake loading conditions. Methods of analysis are considered here for constructional, impounding and seismic loads. Seismic results for the Conwap rockfill dam of the Casecnan trans-basin project, Philippines, are presented, and the difference in embankment response to two different earthquakes, with the same peak acceleration, is illustrated.
