| Abstract: | In the present paper,full load-dispalcement curve and failure characteristics of the unconfined cemented soil reinforced with nanometer silica fume in compression are analyzed.Based on a series of circulating load-unload tests,evolution laws of damage variable for the cemented soil reinforced with nanometer silica fume are studied,then the influence of the nanometer silica fume addition ratio on the damage properties are discussed.Finally,some conclusions are given,which will be used to study reinforcement mechanism of nanometer silica fume in the cemented soil. |
