Earthquake resistance of sloping core dams
WebMar 1, 2016 · Based on the model test results, the earth core rockfill dams were inherently resistant to earthquake due to their ductility. The same shaking table was later used by Seed and Clough [9] to study the earthquake resistance of sloping core dams with model scale of 1/300 and model height of 66 cm. Tests were conducted on models with sandy … 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.
