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 -

According to the geological conditions of baise project, erosive bands and joint fissures, f6 fault and grout curtain are fully simulated to establish 3d numerical model of the dam and its foundation. 3d non - linear fem is used to analyze the stress and strain and to appraise the operation state of both the dam and it ' s foundation under different operation conditions. by overloading the upstream water level and reducing rock strength parameter, the dam foundation ' s degradation process is simulated and the damage pattern and paths are determined, and finally the safety factor is determined
2 、根據百色的地形地質條件，充分模擬了蝕變帶、節理裂隙、 f6斷層、灌漿帷幕等，較為真實地建立了壩體與地基相互作用的整體三維數值模型；採用有限元法對壩體及壩基在不同工況下的應力應變狀態開展分析，評價各工況下壩基的運行狀態；而後採用超載法和綜合法對大壩穩定性進行分析，模擬壩基的漸進性破壞過程，從而得到壩基在超載和強度下降過程中的破壞模式和破壞發展路徑，最終確定壩基超載安全系數和綜合安全系數。 -
The general rule of fissure development in low dip soft - hard interbedding rock mass is described, and then based on this the dam foundation seepage is simulated with dual - medium model, and the influence of unstratabound fissure and waterproof curtain is discussed
摘要闡述了緩傾軟硬互層狀巖體中裂隙發育的一般規律，在這個基礎上採用雙重介質模型對層狀壩基滲流進行了模擬，討論了軟巖層中切層裂隙的發育以及嵌入軟巖帷幕對壩基滲流場的影響。 -
For example, after the collapse of ditong dam in idaho, may 5, 1976, it was found that it was not impervious very well, the impervious curtain was built poorly. when the seepage went through the impervious curtain, the exit water from the pervious material of the downstream or the right side of dam through the foundation or certain line between the foundation and the dam caused contact scour and piping
如美國愛得華州提堂壩於1976年5月5日潰決，事後調查分析，因壩基透水性大，防滲帷幕施工質量差，滲流穿透帷幕，經地基或地基與壩的接觸面從壩體下游側透水料區逸出或從右壩肩繞滲經下游壩體逸出，出逸的水流引起了接觸沖刷和管涌，導致潰壩。 -
