Cement-gravel core material with clay cement and gravel as the primary ingredients is a new core material for embankment dam, and it is generally perceived to have broad applications in the field of dam construction since the stress-strain behavior of such core material is between gravelly soil core and rockfill. Through the triaxial CD test of this material with different cement mixing ratios(wc), the effect of cement mixing ratio on the stress-strain behavior is experimented. The results indicate that the axial deviatoric stress-axial strain and volumetric strain-axial strain curves of this material exhibit softening and dilatancy in different degree respectively as cement mixing ratio increasing. Given the same cement mixing ratio, the peak strength performs almost linearly with an increase of confining pressure. The same pattern is also applicable to the internal friction angle as cement mixing ratio increasing. In addition, the cohesion and secant modulus significantly increase as cement mixing ratio increasing. The research results can provide limited technical support for mechanical properties of cement-gravel soil applied to the core material of high earth-rockfill dam.
