| 摘 要： | 通过对路基填料粉质中液限粘土和粉煤灰土的动力循环荷载试验,分析了粉质中液限粘土和粉煤灰土1:2的动力特性,并进行了比较,得出了动剪强度与循环荷载次数间的变化规律,动模量与动应变的关系表达式,粉煤灰土1:2动剪强度好于粉质中液限粘土,可以作为路基填料。

| Abstract: | By a seies of dynamic cyclic triaxial shear tests on middle-liquidity limit sility clay and fly ash soils(1:2) of roadbed fillings,the dynamical characteristics of middle-liquidity limit sility clay and fly ash soils(1:2) are analyzed and Compared.The characteristics of the two materials,the variety law between the dynamic shear strength and the number of circular load is educed.Then the relationship formula of the dynamical elastic modulus and elastic strain is set up.It is found that the fly ash soils(1:2) is better than middle-liquidity limit sility clay in the dynamic shear strength.It has superiority as roadbed fillings. |
