Numerical Analysis on Mechanics of Interaction Between Slurry and Soil in Earth Dam by Splitting Grouted

Based on the fluid-solid coupling by using the numerical analysis, the mechanics of interaction between slurry and soil in earth dam by splitting grouted are studied. Considering the seepage of slurry in the dam, the Mohr-Coulomb Hardening constitutive model is adopted in this paper through analyzing the pore pressure, stress and strain of the earth dam. It is founded that the slurry by splitting grouted is distributing as earth dam axis as the center and diffusing around. The stress of earth dam is improved by the quadratic stress regulation. Because of the interaction between slurry and soil, the horizontal displacement of earth dam by splitting grouted is generated. Those cause the cracks at the dam abutment.
