摘要

为研究粉煤灰土作为路基填料的可行性，把易液化的粉煤灰和易冻胀的粉质黏土按干重1:2混合，通过冻融循环后的动三轴试验，研究了粉煤灰土的动力特性，得出了动强度和循环荷载次数及冻融循环次数的数量关系，以及动模量与动应变及冻融循环次数的关系曲线。研究表明，粉煤灰土经过3次冻融后的动力性能指标优于粉质黏土，具有良好的抗冻性及稳定性，可以作为季冻区路基填料。

Abstract

Tests on composite material from easy liquefaction fly ash and easy freezing silty clay according to dry weight 1:2 are conducted to investigate the dynamic properties of fly ash soils for roadbed filling. The dynamic triaxial tests are made on the two kinds of soils after freeze-thaw cycles. The variation law between the dynamic strength and the number of cycles of dynamic loading and the number of freeze-thaw cycles is obtained. The relationship curves of the dynamic stress-strain and the dynamic elastic modulus-elastic strain and the curve of the dynamic modulus and the number of freeze-thaw cycles are also given. The research shows that the dynamic properties of fly ash soils(1:2) is better than silty clay subjected to freeze-thaw cycles. After 3 cycles of freezing and thawing

its dynamic strength and dynamic modulus reach stability. It has superiority as roadbed filling.
