摘要

通过对路基填料粉质中液限黏土和粉煤灰土的动力循环荷载试验，分析了粉质中液限黏土和粉煤灰土1: 2的动力特性，得出了动剪强度与循环荷载次数间的变化规律以及动模量与动应变的关系表达式。研究结果表明：粉煤灰土1: 2动剪强度优于粉质中液限黏土，可以作为路基填料。

Abstract

Based on the triaxial tests of middle-liquidity limit silty clay and fly ash soils (1:2) of roadbed fillings

the dynamical characteristics of middle-liquidity limit silty clay and fly ash soils(1:2) are analyzed. Compared the characteristics of the two materials

the variation 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 silty clay in dynamic shear strength. It has superiority as roadbed fillings.
