Abstract

A major embankment dam, approximately 140 feet high and over one mile long, is located in a zone of moderate seismicity in Eastern Kansas. It was determined that slightly cohesive soils and fine sands in the foundation are vulnerable to significant loss of strength by liquefaction during a potential strong earthquake. Numerous seismic retrofit solutions were studied, including the extreme options of “no action” and “replace embankment”. The recommended solution, which is currently designed in detail, considers jet grouting for foundation soil stabilization under the upstream slope and deep soil mixing under the downstream slope.

Evaluation of Alternatives for Earthquake Hazard Mitigation of an Embankment Dam in Kansas
