ABSTRACT
This study investigated the effect of pore structure due to suffusion on the behavior of soil specimens by replacing some of the fine-grain content of the specimens with a chemical fertilizer that dissolves in water. In monotonic shear behavior, the fertilizer-replaced samples showed a greater degree of plastic compression in early shear. In cyclic undrained shear behavior, the fertilizer-replaced sample exhibited more shear strain development with fewer cycles. It can be inferred that the pore structure due to the dissolution of fertilizer in water has a different soil structure from that of the basic specimens.
