The distribution of hydraulic head on the dam foundation plane with curtain grouting is analyzed by the simplified one‐dimensional seepage model, also is studied the effect of various parameters of curtain grouting on seepage pressure on the foundation plane. The theory of the optimum thickness of curtain grouting is proposed from the viewpoint of the minimum seepage pressure resultant and proved by the two‐dimensional seepage model and the finite element method, which includes two cases of homogenous foundation and layered foundation.
