摘　　要：输水涵管作为水库枢纽“三大建筑物”之一,大部分穿坝而过,一旦出现隐患将直接危及大坝安全。涵内套管是一种施工便捷、经济实用、安全可靠的方法,中小型水库多凭工程经验进行套管加固。就此结合从化某水库除险加固工程,分析其过流能力和结构内力,并对内套钢管直径、厚度、原涵管加固、新旧管结合面处理等进行设计,如此可有效消除原涵管存在的安全隐患。The culvert is one of the"three constructions"of the reservoir pivot.Most of the culvert pass through the dams.Once an accident occurs,it will directly endanger the safety of the dam.Casing pipe,as a cheap and easy construction,is an effective method to reduce the risk.Small and medium-sized reservoirs are designed by engineering experience.Combined with practical projects,using overcurrent capacity and structural internal force analysis,the authors put forward their designs of the diameter、thickness and reinforcement of original culvert pipes,which can effectively eliminate the hidden safety danger existing in the original culvert pipe.
