中文摘要 | The stability problem of water-filled dump slope becomes one of the geotechnical engineering problems needed to be resolved. Especially, the couple effect of seepage and damage has a great influence on the dump slope. Using a combination of theoretical analysis and numerical calculation methods, the seepage-damage coupled mathematical model of coal rock mass based on pressure and shear type and open type is established, the permeability tensor affected by fracture damage of coal rock mass is studied. Taking Heidaigou dump slope for example, the stability of water-filled dump slope under the couple effect of seepage and damage is numerical analyzed. The results show that: (1) The pore water pressure of water-filled dump is not fully dissipated under high-stress load, and the damage degree of dump bed and the instability chance of dump slope are increasing. (2) As the water level rises, the pore water pressure increases, the safety factor of dump slope is reducing. The effective internal friction angle and the shear strength decrease when the settling velocity is greater than the pore water pressure dissipation rate. But, the shear strength decrease significantly when the pore water pressure dissipation is too late. The research results provide strong guidance for the stability of water-filled dump slope. |
