Research on the Deformation of Anti-seepage System Considering Fluid-Solid Coupling
Based on the fluid mechanics in porous medium and the theory of fluid-solid coupling, a fluid-solid coupling mathematical model of deformation problem of anti-seepage system in landfill has been established, and the deformation features with water and leachte head in garbage dump layer decreased has been simulated. Results show that with the water head decreased, the pore pressure is progressively lowered, which makes virtual stress increase. Therefore, the displacement of anti-seepage system increases. While the water pumping capacity in certain situation, the increasing of time will lead to the displacement increase at the same one-point position, the increasing of distance will lead to the displacement decrease at different-point position. Impervious layer should be adapted to the uneven settlement caused by the rot and displacement of the waste. It not only provides a reliable theoretical basis for increasing the landfill capacity, but also gives reference to the stability and protection of the landfill.
