Study on shear strength test of fly-ash soil

LI Chang-yu,et al.(School of Civil Engineering,Changchun Institute of Technology,changchun 130012,China)  
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.
