摘　　要：云南某水电站扩机工程进水口与主电站工程同期建成。根据最新装机规模论证结果,装机容量扩大,因此,需要重新复核电站进水口设计。笔者结合扩机工程最新装机规模,重新复核电站进水口水力学及结构布置,并采用有限元法对进水口结构进行静动力计算分析以及边坡稳定计算分析。结果表明,在最新装机规模和设计边界条件下,进水口结构应力及边坡稳定均满足规范要求。该研究成果对类似工程具有一定的参考价值。The intake of a hydropower station expansion project in Yunnan was built at the same time as the main power station project.According to the latest installation scale demonstration results the installed capacity of the expansion project has been expanded.Therefore it is necessary to recheck the design of the hydropower station intake.Based on the latest installation scale of the expansion project the authors recheck the hydraulic and structural layout of the hydropower station intake and use finite element method to conduct static and dynamic analysis of the intake structure as well as slope stability calculation analysis.The results show that the structural stress and slope stability of the intake meet the requirements of the specification under the latest installed scale and design boundary conditions.The research results have certain reference value for similar projects.
