Combined laboratory testing method to determine dynamicproperties of geological material

摘要

The usual way of estimating maximum shear modulus and damping of geologicalmaterial is the resonant column method. However, one of the most practical way to determine themaximum shear modulus in laboratory is the bender element method. A new equipment calledBERC system combining these methods has been developed and used. With this new technique acomplete set of geological material (clay, sand and coarse grained soil) has been subjected to soiltesting.
