摘　　要：针对我国水利水电工程缺少液化等级划分及处理措施针对性差等现状,在分析液化指数法、震陷量计算、液化度法在水利水电工程中应用的基础上,对设防等级、液化程度高的水利水电工程,提出了采用液化度、液化指数的双指标液化等级划分方法,并提出了工程处理措施建议,可为水利水电工程相关规范制订提供参考。In view of the lack of seismic liquefaction classification and poor pertinence of treatment measures in water conservancy and hydropower projects in China,on the basis of analyzing the application of liquefaction index method,collapse amount calculation and liquefaction degree method in water conservancy and hydropower projects,a dual-index liquefaction classification method using liquefaction degree and liquefaction index is proposed for water conservancy and hydropower projects with high safety requirement and liquefaction degree,with suggestions for engineering treatment measures,which can provide reference for the formulation of relevant specifications of water conservancy and hydropower engineering.
