堤防坡率、堤顶宽度、堤基粘土层厚度、前滩地宽度、堤后压盖厚度和宽度等变量的增大，将使堤基渗透稳定的可靠性指标增大；
The reliability index for seepage stability would increase with increasing of slope ratio , crest width , thickness of clay stratum , width of foreland , thickness and width of counter weight blankets , and it would decreases with increasing of the permeability coefficient of sand and clay stratum .
