摘要
根据坝址区地形地质条件、当地天然建筑材料的特性、施工条件等,鱼枧水库工程采用沥青砼心墙堆石坝,心墙沥青砼的级配指数、油石比、填料含量是参考类似工程经验通过试验选择。沥青砼心墙基座底面与基础接触面整个范围内布置固结灌浆,坝基采用帷幕灌浆。坝坡稳定分析成果满足规范要求。
Considering the topographical and geological conditions of the dam site area,the characteristics of local natural construction materials and the construction conditions,the rockfill dam with asphalt concrete core is adopted in Yujian Reservoir project.Based on the experience of similar projects and engineering tests,the gradation index,asphalt aggregate ratio and filler content of the asphalt concrete are selected.Consolidation grouting is arranged for the whole contact surface of the core wall base and the foundation.Curtain grouting is also adopted for the dam foundation.Analysis also shows that the stability of the dam slope meets the specification requirements.
