摘要
本文根据引大入秦庄浪河渡槽的工程数据,建立了渡槽的有限元模型,采用非对称模态提取法求解了4种水深下渡槽的动力特性,用隐式—显式积分算法计算了天津宁河地震波作用下渡槽的动力响应,得出了不同水深下渡槽结构动力响应的变化规律等结论。
According the data in the yindaruqin aqueduct,this paper established the finite element model model of the yindaruqin aqueduct. Considering four depth of water in the aqueduct , the dynamic nature properties of the aqueduct was obtained , and the dynamic response of the large aqueduct under the tianjin ninghe wave. Conclusion of the variation law of the dynamic stress and dynamic displacement of the aqueduct structure under different quantities of discharge is also drawn.
