Abstract

Particle breakage is a theme of great focus on affecting the behavior of granular soil. This paper presents an experimental investigation on the influence of particle breakage on the isotropic compressibility of the precrushed sands using a number of drained isotropic consolidation tests. Particle breakage resulted in movement of the compression lines followed by the rebound lines towards a decrease in the void ratio, implying that particle breakage caused a more contractive soil. Particle breakage impaired the bulk deformation modulus by increasing the compression coefficient for the compression behavior of the precrushed sands, but showed a complex effect on the bulk deformation modulus and rebound coefficient for the rebound behavior of the precrushed sands. However, particle breakage caused an increase in the compression indexes of the precrushed sands but showed a complex effect on the rebound indexes of the precrushed sands. In the e−p′ plane and the e−logp′ plane, the compression lines and rebound lines of the precrushed sands were curved. A generalized model was proposed to straighten the compression and rebound lines of the precrushed sands in the e − (p′/pa)α plane. Particle breakage resulted in a general rotation and translation of the linear compression and rebound lines of the precrushed sands in the e−(p′/pa)α plane. The critical state line and isotropic consolidation line on the loosest state of silica sand no. 5 were curved in the e−logp′ plane but straightened in the ep′α=0.7 plane. In the ep′α=0.7 plane, a reasonable linear critical state line of silica sand no. 5 was proposed by adjusting it to match the isotropic consolidation line on the loosest state.
