摘　　要：水电站地下厂房支护设计，大都以工程类比法为主，辅以各种理论分析。小浪底工程地下厂房设计时，在对围岩进行分类的基础上，采用直接对比法、间接类比法、Ｑ系统分类等方法进行综合分析，确定各洞室的间距及其喷锚支护参数。有限元计算验证和工程实践表明，支护型式和参数是合理的，可以确保工程的安全。he design of support system of underground workshop of a water power station mainly adopted project analogism and was supplemented with theoretical analysis. On the basis of classification of wall rock,the spaces between holes and coefficients of rock support were determined by integral analysis such as direct analogism,indirect analogism and Q-system classification method in the design of underground workshop of Xiaolangdi project. Limited unit calculation and project practice verified that types and coefficients of bracing system are reasonable and can ensure the security of the project.
