- 1. Significantly wide transition and drainage zones in the embankment of material not vulnerable to cracking.
- 2. Controlled compaction of embankment zones to enhance dynamic performance.
- 3. Removal or treatment of foundation materials of low strength or density.
- 4. Enhanced ability to drain reservoir.
- 5. Flare the embankment core at abutment contacts.
- 6. Locate the core to minimize saturation of materials.
- 7. Stabilize slopes around the reservoir rim.
Design of new dams should include measures, which provide multiple lines of defense, that enhance their performance under seismic loading. Measures may include:
KEY: dams, earthquakes, floods, reservoirs
