动剪切模量 meaning in English
dynamic shear modulus of soils
Examples
- The framework and results of this study is thus summarized as follows : 1 . analyzing the effect of the nonlinear parameters on seismic response . so far the g / g _ max - ( transient dynamical shear modulus over the maximum shear modulus vs . shear strain ) and the - ( equivalent shear hysteretic damping ration vs . shear strain ) curves are widely employed in the experimental method in studying soil dynamic property , supposing under equiamplitude cyclic load
目前，人们利用实验手段分析土体动力特性时给出的最基本的描述量是g g _ ( max ) ?曲线(等效动剪切模量与最大动剪切模量的比值随应变幅值变化的曲线)及?曲线(等效剪切滞回阻尼比值随应变幅值变化的曲线) 。 - The influences of soil structure , confining pressure and strain amplitude on dynamic properties of recently deposited soils of nanjing and its surrounding areas are discussed . furthermore , based on test results and theoretical analysis , the averaging curves , recommended values and envelopes of dynamic shear modulus ratio ggmax and damping ratio versus dynamic strain for recently deposited soils of nanjing and its surrounding areas are presented . by use of vibration triaxial apparatus , nanjing silty clay and fine sand interbedded strata and nanjing fine sand were tested and their test results are discussed
