摘要
文中分析了强迫振动下的鞭梢效应和地震作用下鞭梢效应的成因,推导了鞭梢效应的理论公式,研究了鞭梢效应对结构变形和应力的影响,讨论了建筑物上突出结构对主体结构的减震作用,并且通过三峡升船机的例子,阐述了利用鞭梢效应来减振在大坝安全方面的应用,从而为坝工设计提供更可靠的依据。
The paper analyzes the causes of whiplash effect under the condition of the forced vibration and earthquake,deduces the theoretical formula of whiplash effect,studies the influence of whiplash effect on the structure deformation and stress and discusses the vibration reduction influence of prominent structure of the building on the main structure.Take the ship lift of the three gorges project as an example,the paper describes the application of whiplash effect to reducing the vibration in the dam safety,which supplies the reliable basis for the design of dam construction.
