摘要
牛头溪水库拱坝基础地质条件十分复杂，构造较多且规模较大，由此带来坝肩稳定、基础不均匀沉陷、深层渗漏等问题。对此，因地制宜地设计采用抗剪键、置换混凝土垫块加锚筋，设置深孔固结灌浆加钢筋网等措施，施工简单，投资节省。经过二年多来的洪水考验，证明工程措施安全可行。
The arch dam base geological condition of the Niutouxi reservoir is very complicate with varied and large scale structures and problems of dam abutment stability and base uneven sinking and deep layer percolation. Therefore, the measures of shearing resisting key, instead of concrete pad plus anchor bar and deep hole solidified grouting plus bar net have been adopted in construction of the dam. The construction of the measures are simple and capital saving. The examination of over 20 years flooding have proved that the measures were sa fly and feasible.]
