Earthquake resistance of sloping core dams

WebDuring earthquake shaking abutments and foundations may shift and move allowing the dam to tilt, rotate, or slide and lose structural integrity. Slope failures on or near the dam may allow the reservoir to overtop the dam or failure material to block spillways and outlets.

The distribution of the hydrodynamic pressure along the upstream face is determined. WebThe width of the core is restricted to that necessary to lower sufficiently the pore pressures in the downstream part of the dam. Although the top of the core must be at the crest of the dam, the core itself need not be vertical. On some rockfill dams the core can slope forward to an extreme position where it lies on the upstream face. flash cards kindergarten
