چکیده مقاله

This paper reviews empirical methods to estimate deformation modulus as one of the most important parameters required to build numerical models for many rock engineering projects such as slope stability, dams, tunneling and underground excavations. This parameter can be obtained by field tests directly, but these are time consuming and expensive. Therefore, an indirect method can be useful for engineering projects. Usually, the empirical estimations are presented using regression methods such as linear, nonlinear, power and polynomial function. On the other hand, some researchers used soft computing techniques including ANN and GP. The aim of all studies is to presenting an equation based on intact rock properties and classification systems. In the early studies, RMR classification system was used for prediction. Then, some researchers used other classification systems like Q and GSI in addition to RMR. Recently, studies are carried out using intact rock properties such as modulus of elasticity, UCS and joint properties by regression methods and soft computing techniques. Consequently, we have several equations that can improve the understanding of rock masses.
