根据栈桥设计标准中的工作状态和非工作状态两种工况分别进行了相应流场参数计算,并利用判别理论,对杭州湾南岸栈桥钢管桩是否会发生涡激共振进行了判断。在非工作状态下考虑了十年和二十年一遇标准两种情况,在钢管桩的自振固有频率计算中,考虑了流体附加质量和局部冲刷深度;结合结构及施工情况,对可能发生涡振的钢管桩提出了有针对性的技术措施。 According to the working condition and the non-working condition in the design standards of trestle, the corresponding flow field parameters are respectively calculated and the judgment theory is used to judge whether vortex-induced resonance occurs in the steel-pipe piles on the south bank of Hangzhou Bay. Under non-working conditions, two cases of one-year and one-year standards are considered. In natural frequency calculation of natural vibration of steel pipe pile, the additional mass of fluid and local scour depth are considered. According to the structure and construction conditions, Vortex vibration of steel pipe pile put forward a targeted technical measures.
