摘　　要：以沙河涵洞式渡槽为研究对象,采用有限单元法建立涵洞式渡槽结构计算模型,分析了自重、渡槽及涵洞的水压、人群荷载、扬压力、风荷载及温度荷载等单荷载因素对渡槽位移的影响,研究了涵洞式渡槽应力及位移变化规律。This paper takes the culvert aqueduct of Sha river as the research object,the finite element method is adopted to establish the calculation model of culvert aqueduct structure.The influences of single load factors,such as structure weight,water pressure of aqueduct and culvert,crowd load,uplift pressure,wind load and temperature load,on the displacement of aqueduct are analyzed.The stress and displacement of culvert aqueduct are studied.

关 键 词：涵洞式渡槽 单荷载因素 有限元法 应力分析 竖向位移
