【摘要】：考慮地基和不同邊界條件,選用時程分析方法,應(yīng)用有限元軟件ANSYS對某水閘結(jié)構(gòu)進行動力分析,結(jié)果表明:地基不僅對水閘閘室結(jié)構(gòu)動位移有放大作用,而且還延遲了閘室結(jié)構(gòu)的地震動位移,但對水閘的機架橋和啟閉機房影響很小。另外地基不僅放大了水閘結(jié)構(gòu)的動應(yīng)力響應(yīng),而且還延后了水閘結(jié)構(gòu)地震動應(yīng)力的出現(xiàn),其對水閘閘室結(jié)構(gòu)的放大作用最大,機架橋次之,啟閉機房最小。
[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.
