This study was undertaken to determine the factors that lead to instability in clay shale, and thus to provide a basis for assessing the probable long-term stability of high crater slopes in clay shales. The conclusion is reached that future design crater slopes must be based on experiences with conventionally excavated slopes. Furthermore, the design of cratered slopes must be conservative, although no experience indicates that the slope inclination must be as flat as the residual angle of internal friction of the site materials.

This report compares various laboratory procedures and equipment used for determining the residual strength of clay shales. The effects of testing apparatus, specimen type, normal load, and rate of displacement on the residual strength of various clay shales were evaluated by relations between residual strength and Atterberg limits, grain size, and mineralogy were examined.

This report was previously submitted (April 1978) by the author to the University of Illinois in partial fulfillment or requirements for the degree of Doctor of Philosophy in Civil Engineering. The reported work was conducted as an adjunct study to a long-term and broad effort entitled 'Study of Clay Shale Slopes Along the Panama Canal' conducted by personnel of the U.S. Army Engineer Waterways Experiment Station under the author's supervision. The work consists of a documentation of a case history in which the occurrence and nature of initial failures or 'breaks' were described and pin-pointed with respect to time, location, and extent; the geological setting and groundwater conditions were described; physical tests, with emphasis on laboratory determination of strength parameters, were conducted; and back analyses were conducted along nine cross sections constructed through six initial breaks to compare the required field strength parameters with parameters determined in laboratory tests. Important results and conclusions from this Supplemental Report as well as Reports 1, 2, and 3 of the series will be presented in Report 4, which summarizes the overall study.
