输水涵管是实现水库灌溉、供水、发电等运行功能的关键建筑物。通过分析研究小型水库输水涵管病害特征、加固技术方案及其主要的关联因素，归纳总结出输水涵管主要病害类别和主要加固技术方案，提出了输水涵管加固技术方案主要的关联因素为涵管断面尺寸、涵管埋设深度和工程地质条件，并结合工程实例，讨论了涵管加固方案比较选择的方法和思路。

 Aqueducts are essential structures in reservoirs to irrigation, water supply, power generation, etc. In this paper we analyze the typical symptoms, reinforcing solutions and relevant factors of defective aqueducts in small reservoirs ； summarize the main disease categories and reinforcing solutions of aqueducts ； present the opinion that the critical relevant factors of reinforcing solutions for aqueducts are the size of cross section, the laying depth and the engineering geologic condition ； thus provide ideas and approaches to select the appropriate aqueduct reinforcement solutions
