An Investigation of the Mechanisms Involved in Plate Load Testing in Rock

Accurate determination of rock mass deformation modulus is very important in engineering projects. The plate loading test (PLT) a method that generally used dam construction projects to determine modulus. Numerical simulation was investigate the mechanisms involved this test. first objective paper employ 3D modeling interpretation load tests conducted at Bazoft site Iran. Additionally, parametric study effects key parameters such as displacement measuring depth and diameter on results another study. moduli values determined numerically were compared against actual filed testing data from in-situ site, ISRM suggested formula. analysis showed optimum measurement for calculation approximately equal depths beyond one can be unrealistic. Moreover, have significant effect results. As increases, increase much more rapid pace when employing smaller size plates.
