【摘要】：考虑地基和不同边界条件,选用时程分析方法,应用有限元软件ANSYS对某水闸结构进行动力分析,结果表明:地基不仅对水闸闸室结构动位移有放大作用,而且还延迟了闸室结构的地震动位移,但对水闸的机架桥和启闭机房影响很小。另外地基不仅放大了水闸结构的动应力响应,而且还延后了水闸结构地震动应力的出现,其对水闸闸室结构的放大作用最大,机架桥次之,启闭机房最小。
[Abstract]:Considering the foundation and different boundary conditions, the dynamic analysis of a sluice structure is carried out by using the finite element software ANSYS and the time-history analysis method is selected. The results show that the foundation not only amplifies the dynamic displacement of the sluice chamber structure, but also increases the dynamic displacement of the sluice chamber structure. The ground motion displacement of the sluice chamber structure is also delayed, but it has little effect on the frame bridge and the hoist room of the sluice. In addition, the foundation not only magnifies the dynamic stress response of the sluice structure, but also delays the emergence of the ground motion stress of the sluice structure, which has the greatest effect on the sluice chamber structure, followed by the frame bridge and the opening and closing machine room.
