摘要

通过水泥土-粉土复合试样的动三轴试验，研究了动荷载作用下围压、置换率及初始干密度对复合试样动弹模量的影响。结果表明：经过置换后，复合试样的动弹模量得到提高；动应力-应变关系曲线符合双曲线模型；动弹模量和应变相关曲线与纯粉土的有关曲线形状相似；水泥土-粉土复合试样的动弹模量随应变水平的增长而降低；在相同的动应变水平下，随围压、置换率及初始干密度的增大而增大；在围压较小时，置换率、围压和干密度对动弹模量的影响更显著；复合试样的最大动弹模也随围压、置换率、初始干密度的增大而增大；归一化后的曲线分布在一个相对狭窄的范围内。

Abstract

Based on dynamic triaxial tests

the dynamic elastic modulus of cemented silt-silt composite sample is studied with the influences of confining pressure

replacement ratio and initial dry density. The results show that the dynamic modulus of composite sample is much higher than that of pure silt. The relationship of dynamic elastic modulus versus strain is similar to that of pure silt. The dynamic elastic modulus of cemented silt-silt composite sample decreases with strain increasing. At the same strain level

the elastic modulus increases as the confining pressure

the replacement ratio

and the initial dry density increase. The influence of replacement ratio

confining pressure

and the initial dry density on modulus is significant at low confining pressure. The maximum dynamic modulus of composite sample increases as the confining pressure

the replacement ratio

and the initial dry density increase. The curves exist within a narrow area.
