摘要
为简化水电站有压隧洞经济直径计算工作，提高工程建设的动态经济效益，推导了按动态经济分析方法确定水电站不衬砌有压隧洞经济直径的公式，并以实例作了论证。
The calculation formula of dynamiceconomic diameter of a non-lined pressure tunnel of a hydro-power station has been derived according to dynamic economic analysis method for simplifying calculation of economic diameter of pressure tunnel of a hydro-power station and enhancing dynamic economic benefit of project construction.
