Abstract:The determination of effective elastic tensor is very important for civil engineering researchers;and it is essential to calculate the effective elastic tensor in order to obtain the rational results. Four kinds of methods for current effective elastic tensor determination are shown:volumetrical average method,self-consist method,Hashin-Strikman method(upper limit method) and Hashin-Strikman method(lower limit method) for every component in the effective elastic tensor. Based on the homogenization technology,the formulae of macroscopic effective elastic tensor are obtained for stratified isotropic geomaterial under the condition that the displacement and stress are equal in the everywhere in the element. And the proposed equation can be simplified as the formulae of volumetrical average method and self-consist method under some special cases. The comparative analyses of five different methods are performed;and the calculation results show the proposed method can describe the parallel flow model and series flow model. The upper-lower limit values of every component of effective elastic tensor are not determined by Hashin-Strikman method;and the lower limit scope can be decided by self-consist method. However,the upper limit scope can be determined by Hashin-Strikman method except . The obtained results are very important for calculation and analysis of rock slope and dam foundation engineering.
