Abstract : The report is primarily concerned with the development of laboratory test procedures for the determination of rational design strengths of intermediate quality rocks. Rocks tested were principally from Stockton and Kaysinger Dams and included the softer dolomites, compacted shales, weakly cemented breccias, and weaker layers within hard rocks where the strength is sufficiently low to often be a key factor in the design of superimposed structures of concrete and earth. This report demonstrates the need for considerable testing in order to arrive at reliable average strength values because of the wide variations in structure of this kind of rock. Also included are detailed rock testing procedures along with pertinent comments relative to their use. (Author)
