- Concrete anti - seepage wall are penetrated through the alluvial layer with high water permeability and put in the relative impermeable layer
混凝土防滲墻穿過透水性強的沖積層，置于相對隔水層內。 - 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，其余部分均予以保留.斷層破碎帶處理，趾板部位采用混凝土塞，其它部位采用半透水料置換，并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、便于施工的目的，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 - 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
介紹碧蓮水電站攔水壩系軟基上的水力自控翻板閘門溢流壩工程特點和設計原理.閘門利用水力和杠桿原理實現自控關閉；閘壩平時擋水發電,洪水期自動翻倒泄洪沖砂,有效地解決洪水對上游庫區實物的淹沒損失及水庫泥沙淤積問題；閘壩采用地下混凝土連續墻進行地基防滲處理及面流消能，消能效果顯著，工程投資少.本工程設計可供其它建固定壩淹沒損失過大或在軟基上建低重力式堰壩的類似工程參考
