| 摘 要： | 文章介绍了一种以锯末为主要成分,用于地基-基础-上部结构动力相互作用振动台模型试验的混合地基土。用循环单剪仪对混合地基土进行了动力特性试验,得出了动剪切模量比Gd/Gdmax和阻尼比λ随动剪应变γd变化的关系曲线,给出了该种混合地基土的动力特性参数。 |
| 关 键 词： | 动剪模量 阻尼比 循环单剪试验 模型试验 |

| Abstract: | A kind of model soil which is mainly composed of sawdust is designed.The aim of such design is to use such soil in the shake table test of the soil-foundation-structure system. Cyclic simple shear testing is conducted on the specimens of both the site soil and and the designed soil, and the curves of dynamic shear modulus ratio G__d/G__(dmax) and damping ratio versus dynamic shear strain of the designed model soil and the corresponding parameters are presented. |
| Keywords: | dynamic shear modulus damping ratio cyclic simple shear test model test |
