Study on Particle Breakage of Coarse-Grained Soil Based on Large-Scale Triaxial Test

Abstract:

Using large-scale shearing device, isotropiclly consolidated-drained triaxial test under different confining pressures are performed for overburden material of ShuangJiangKou earth dam which relative density is 0.8. The relationship between particle breakage of coarse-grained soil and input plastic work under loading and between particle breakage and confining pressure and between particle breakage and strength of coarse-grained soil. The results show that the particle breakage of coarse-grained soil and the input plastic work under loading is closely related. The particle breakage of coarse-grained soil increase with the input plastic work and there is a relationship of power function between B_g and W_p. the increase of confining pressure will lead to the increase of particle breakage of coarse-grained soil, and there is a relationship of power function between B_g and . the increase of particle breakage of coarse-grained soil will lead to the decrease of strength of coarse-grained soil, and a relationship of linear between B_g and φ.
