【摘要】 采用有限元方法对沙河大型预应力矩形渡槽施工、运行过程进行受力分析,给出了施工、运行过程中不同断面几个特殊点的应力变化曲线,讨论了最大拉、压应力出现的部位,并对几个特殊的应力变化曲线进行比较后知,沙河渡槽的强度在施工、运行过程中是绝对安全可靠的.更多还原

【Abstract】 The finite element method is adopted to the stress analysis of construction and operational processes in the Shahe large-scale prestress rectangular flume,it is provided that,the variation stresses charts of particularity points in diversity section during the construction and operational processes,the positions of the maximam pull and press stresses are discussed,and comparing with several special stress variation curves,the result is got that,Shahe flume is absolutely safe and reliable in !the strength.更多还原
