It is also found that the effects of thickness and shear modulus of the inhomogeneous soil are significant but the effects of the material damping are not significant.
水平方向不均匀土的剪切弹性模量的影响较大而其材料阻尼的影响较小。
The dynamic shear modulus ratio and damping ratio of soil are indispensability for seismic safety evaluation and soil layer seismic response analysis of engineering sites.
土的动剪切模量比和阻尼比是工程场地地震安全性评价工作和土层地震反应分析中不可缺少的重要参数。
Dynamic triaxial test is mainly used to determine the dynamic shear modulus & dynamic damping ratio of soil, which are the important parameters for seismic response analysis.
动三轴试验主要确定土的动剪切模量和土的动阻尼比，而这些参数又是地震动反应分析中的重要参数，该参数的取值小直接影响了桥梁的勘察设计。
