Seismic Analysis Method of Deep-Water Bridge Pier and Water Coupling

摘要

摘要: 为正确采用动水压力计算方法,提出了一种新的深水桥梁墩水耦合计算方法结合法,即将Morison方程与计算流体力学相结合,分析深水桥梁墩水耦合抗震问题.ANSYS-CFX模型计算表明:结合法能较好地进行墩水耦合抗震分析;深水环境使墩顶最大弹性位移减小,最大刚体位移增大,结构整体变形增大;刚体运动附加动水力对桥墩起主要作用,但应同时考虑弹性振动引起的动水压力.

Abstract: To adopt a right method to calculate hydrodynamic pressure, a novel method, combining the Morison equation with CFD (computational fluid dynamics), for calculating the seismic responses of a deep-water bridge under pier-water coupling was proposed. The results based on the ANSYS-CFX model show that the proposed method can calculate the seismic responses of a deep-water bridge under pier-water coupling effectively. A deep-water environment will decrease the maximum elastic displace-ment at pier top, but it will increase the maximum rigid displacement and the total stsructure displacement. Additional hydrodynamic pressure generated by rigid motion plays a major role, and the effect of elastic vibration must be considered.
