| 10. | 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
简要论述泽雅水库面板堆石坝坝基处理和防渗的原则及设计要点.趾板基础和堆石体各区砂砾石基础开挖，除趾板与其下游1 / 9底宽范围以及坝脚挖除冲积层至弱风化(局部微风化)基岩外，其余部分均予以保留.断层破碎带处理，趾板部位采用混凝土塞，其它部位采用半透水料置换，并根据本工程特点在下游坝脚加设了反滤层.为提高坝基的整体性和防渗性能，对趾板进行了固结和帷幕灌浆.达到了安全、经济、便于施工的目的，运行情况良好，可为面板堆石坝的设计和研究提供参考与借鉴 |
