摘要
以引水隧洞洞径为自变量,以项目在计算期内获得的最大收益为目标函数,通过分析发电收入、引水隧洞工程建设投资与洞径的关系,建立了经济洞径的目标函数表达式,通过求解目标函数的最小值来获得引水隧洞的经济洞径。方法概念清晰,理论严谨,计算工作量小,工程适用性强,可为引水隧洞工程设计提供有益参考。
This article takes the diameter of the headrace tunnel as the independent variable and the maximum profit obtained by the project during the calculation period as the objective function.By analyzing the relationship between power generation income,construction investment of the headrace tunnel and the diameter of the tunnel,an objective function expression for the economic diameter of the headrace tunnel is established.By solving the minimum value of the objective function,the economic diameter of the headrace tunnel is obtained.The method has clear concepts,rigorous theory,low computational work,and strong engineering applicability,which can provide useful reference for the design of headrace tunnel.
