R655-11-5D. Design Measures

Design of new dams should include measures, which provide multiple lines of defense, that enhance their performance under seismic loading. Measures may include:

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.
