心墙土料的动力参考剪应变
Dynamic reference shear strain for core wall materials in earth dams
摘要
Abstract
Reference shear strain is a generalized parameter of the curve of dynamic shear modulus ratio versus dynamic shear strain of soil, and traditionally it has been calculated by the definition as the ratio of maximum dynamic shear stress over maximum dynamic shear modulus. This paper proposes two new methods that use normalized dynamic shear modulus ratio curve and solution of linear equations respectively, not involving dynamic strength of the soil. Comparison shows that all the three methods produce similar modulus-strain curves, but the first new method has advantages of clearer conceptualization and simpler calculation.关键词
