Abstract: The penalized Heaviside function associated with the discrete variational inequality formulation of Signorini type is improved, and an adaptive form of the penalized Heaviside function is suggested to further improve numerical stability and overcome mesh dependence of the variational inequality approach of Signorini type. The suggested approach is applied to seepage analysis of the dam site of Gongming Reservoir, Shenzhen, and the effectiveness of the variational inequality approach of Signorini type for complex three-dimensional seepage problems with strong nonlinearity is validated.
