Measurement and Analysis of Rock Physical Properties on the Dez Project, Iran


The foundation rock for the Dez Project is a Pliocene, limestone cobble conglomerate. The construction of a thin-arch dam on this young, heterogeneous material required a thorough understanding of its physical properties. The testing program included: 257 plate bearing tests, 85 in situ measurements of residual stress using the flat jack method, 2 large hydrostatic pressure chambers, and laboratory tests on 887 six-in.-diameter rock cores. The application of the principles of rock mechanics resulted in considerable savings in time and money on the Dez Project.
