A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved

Ordinary it takes over 30 % cost of total irrigation buildings. in seasonal frozen soil area, frozen heave produces frozen - heave forces on the slab - foundation. it often make the slab - foundation damage due to bending, twisting and growth - up if the construction is build following non - frozen soil design methods
季節凍土區涵閘工程是水利工程建設中常見的一種結構，一般占水工建築物工程造價的三分之一以上，在季節凍土區由於土凍結后產生的凍脹，對
板基作用有凍脹力，所以按照融土壓力設計的
板基經常發生彎曲、扭轉、上抬等破壞。
