Measurement of Rock Mass Deformation Moduli at the Abutments of a Concrete Dam
A site investigation program was carried out in for a concrete dam construction Iran. The investigations are aimed to provide geotechnical parameters in order to analyze the suitability of this location and also to obtain required design parameters. As part of the program several Plate Load Test (PLT) and Flexible Dilatometer Test (FDT) were carried out in specially prepared galleries. Both tests are based on the theory of elasticity which considers the rock mass as an elastic, isotropic and homogeneous medium. Due to these assumptions, the modulus derived from both tests should be similar. In real conditions, however, this is not the case and the modulus determined from PLT is usually greater than values derived from the FDT. A number of uncertainties are associated with each of the above mentioned tests. The aim of this paper is to discuss the results obtained from these tests and compare the results from the two mentioned methods.
