【 摘 要 】
As an anti-seepage material, geomembrane is widely used in earth-rock dams engineering. However, the seepage calculation of geomembrane earth-rock dams has not been studied theoretically. According to the permeation mechanism of geomembrane, it can be divided into two categories: one is the permeability of itself; the other is the defect leakage flow. Based on the feedback analysis of the observation data of geomembrane of earth-rock dam, the average permeability coefficient of geomembrane is obtained. Finally, the error sources of clay emulation in seepage calculation of geomembrane earth-rock dams are discussed. The counting error is analyzed and the mathematical model is modified.
