摘　　要：通过原体动力试验及有限元计算讨论了佛子岭连拱坝支墩的模态参数及动力特性．原体试验给出了典型支墩的前三阶模态频率、阻尼及振型，并进行了相应的数值计算．试验与计算吻合良好．可以看出，支墩的局部振动接近于二维板的动力特性．其计算模型应以支墩与相邻两拱联合作用为宜．所给结果也可供其它类似的支墩坝或拱壁结构参考．In this paper the modal parameters and dynamic characters of Fuziling multiarch dam are discussed by means of prototype test and calculation by finite element method. The frequencies, dampings and modal shapes of typical buttress for formal three orders are presented by prototype test and corresponding numerical calculation is carried out. The well counsidence between calculation and test is shown. It is shown that the local vibration of the buttress is near the dynamic character of a two dimension plate. The calculation model is suitable to take a buttress combined with two neighbouring two arches. The result presented in this paper can also be refered to other similar buttress dams and structures.
