摘　　要：引水发电隧洞一般采用有压圆形洞,洞径选取需综合考虑工程造价和发电效益。根据洞径与隧洞工程造价、发电效益的关系,采用非参数回归模型求得经济洞径。实际应用结果表明,采用非参数回归模型选取洞径更方便。The cross section of diversion tunnel for power generation is generally round, and the diameter is defined by the construction cost and generating benefits. Based on the relationship of diameter, costs and benefits, the nonparametric regression model is used to determine the tunnel economical diameter. The application shows that selected diameter based on the nonparametric method is more convenient.
