Abstract

The stability of the fine sands underlying the shells of the Revelstoke earthfill dam under earthquake shaking is discussed. The evaluation of liquefaction potential of the deposit was made from the field standard penetration resistance of the material. The dynamic analysis, made by a one-dimensional equivalent visco-elastic method, indicated that the sand under both the upstream and downstream shells had adequate liquefaction resistance and could be left in place. Adequate drainage of downstream fine sands was provided to further reduce its liquefaction potential.

Evaluation of Seismic Stability of Foundation Soils Under Revelstoke Earthfill Dam

St. Louis, Missouri

The stability of the fine sands underlying the shells of the Revelstoke earthfill dam under earthquake shaking is discussed. The evaluation of liquefaction potential of the deposit was made from the field standard penetration resistance of the material. The dynamic analysis, made by a one-dimensional equivalent visco-elastic method, indicated that the sand under both the upstream and downstream shells had adequate liquefaction resistance and could be left in place. Adequate drainage of downstream fine sands was provided to further reduce its liquefaction potential.
