Abstract : The Center Hill Dam on the Caney Fork River, DeKalb County, Tennessee, is an earthfill structure with a concrete overflow portion. A laboratory study was conducted to evaluate the earthquake response of the embankment material. To evaluate the earthquake response, the U. S. Army Engineer District, Nashville, supplied the U. S. Army Engineer Waterways Experiment Station (WES) with undisturbed samples obtained from beneath the center line of the embankment. The samples were classified as either CH or CL soils. Natural dry densities ranged from 95 to 125 pcf. Cyclic triaxial compression tests were conducted on the undisturbed samples. Based on the results of these tests, it appears that the material is relatively stable with respect to liquefaction. Due to the variation in physical properties and dry density, however, it is felt that more tests should be performed if a dynamic finite element analysis of the dam is to be performed. (Author)
