摘　　要：以某水电站进水口渐变段为研究对象,对其进行结构应力分析。通过计算,给出钢衬与坝体间的连接应力及分布状态,提出加强措施保证钢衬与坝体混凝土的联结强度,以防止进水口钢衬与混凝土剥离而使钢衬发生屈曲变形,从而为进水口渐变段钢衬结构的设计提供了理论依据。In this paper the finite element method is adopted to analyze the stress and displacement of the penstock located on the downstream dam surface of a hydropower station. The results obtained in the analysis provides basis for design of penstock. Through the analysis both stress and displacement between the penstock and the dam can be attained. And some measures have been put forward to ensure the connection strength between the penstock and the dam.
