Abstract: The U.S. Army Engineer Waterways Experiment Station (WES), in connection with a dynamic analysis of Fort Peck Dam, conducted a series of dynamic laboratory tests on reconstituted specimens of Fort Peck materials to evaluate their liquefaction potential. From a comparison of these laboratory results with other laboratory results obtained for undisturbed hydraulic-fill material, it was apparent that reconstitution did affect the results. To evaluate more fully this effect, various laboratories and institutions engaged in dynamic testing were contacted in an effort to determine the state of the art in this area. After reviewing the present state of the art, WES conducted cyclic triaxial compression tests on undisturbed specimens from Fort Peck Dam. These specimens were then reconstituted to the as-tested density, and the cyclic triaxial tests were repeated. The test results indicated that the undisturbed specimens were approximately 70 to 80 percent more stable than the reconstituted specimens.
