Abstract

One of the key parameters in analyzing and designing of the underground and geomechanical projects, especially in water pressure tunnels and dams, is determination of the deformation modulus. To evaluate and estimation this parameter, several researches have been conducted using empirical models and rock mass classifications. However, none of these models are capable of accurately predicting the modulus of deformation value. They only predict the initial estimation of this parameter. For this reason, a huge series of in situ tests based on the plate load test were carried out in the Bakhtiari double arch concrete dam, the highest concrete dam in the world. Finally, according to the in situ data analysis, a model to predict the modulus of deformation was presented.
