摘　　要：某水电站坝基基岩为白垩系砂岩,岩石成岩程度低,具有孔隙率大、密度低、透水性强、强度低、抗渗透变形能力差、易扰动破坏等特性;坝基存在渗漏及渗透变形问题;为解决坝基渗漏及渗透变形问题,对坝基进行灌浆试验、渗流计算及工程处理措施分析研究,以确保工程安全,提高投资效益。The foundation rock of a hydropower station is Cretaceous sandstone.Diagenetic degree of the foundation rock is very low,and the rock mass has the characteristics of large porosity,low density,strong water permeability,low strength,poor resistance to seepage deformation,and easy disturbance and damage.The dam foundation has problems of seepage and seepage deformation.To solve the problem of seepage and seepage deformation of the dam foundation,grouting test,seepage calculation and engineering treatment measures were analyzed and researched on the dam foundationto ensure engineering safety and improve investment efficiency.
