  1. 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

    簡要論述澤雅水庫面板堆石壩壩基處理和防滲的原則及設計要點.趾板基礎和堆石體各區砂礫石基礎開挖，除趾板與其下游1 / 9底寬范圍以及壩腳挖除沖積層至弱風化（局部微風化）基巖外，其餘部分均予以保留.斷層破碎帶處理，趾板部位採用混凝土塞，其它部位採用半透水料置換，並根據本工程特點在下游壩腳加設了反濾層.為提高壩基的整體性和防滲性能，對趾板進行了固結和帷幕灌漿.達到了安全、經濟、便於施工的目的，運行情況良好，可為面板堆石壩的設計和研究提供參考與借鑒
