Numerical Simulation of Seepage Control Effects at a Gravity Dam Site

Abstract:

Located at a narrow and deeply-cut valley in the middle reach of Yalong River in Southwestern China, the Kala Hydropower Station is subjected to serious seepage and leakage problems due to complex geological conditions at the dam site. A numerical method combining a substructure technique, a variational inequality formulation of Signorini’s type and an adaptive penalized Heaviside function (short for SVA method) was adopted for the simulation and assessment of seepage control effects at the dam site in Kala Hydropower Project. Numerical modeling of a typical overflow dam section and the whole dam site demonstrated that the primary design was a proper scheme for seepage control, and furthermore, optimization of the seepage control system can be performed in designing the layout.
