摘要:
基于所建立的考虑流固耦合渡槽梁段单元动力分析模型,对单墩渡槽结构振动特性和在地震波下的地震响应进行计算分析.该模型综合考虑了渡槽横向、竖向、纵向、自由扭转和约束扭转变形、以及槽内水体与渡槽槽身的流固动力相互作用的影响.计算结果表明流体和槽身的横向动力相互作用对渡槽的横向低频振动影响较大,对横向高频影响较小.动力分析模型的正确性和可靠性说明该模型是考虑渡槽内水体流固耦合的实用的动力分析模型,计算结果可为大型渡槽抗震设计提供参考.
Abstract:
Based on the established dynamic analysis model considering the fluid-structure interaction aqueduct beam segment, the vibration characteristics of the single pier aqueduct structure and the seismic response under seismic waves are calculated and analyzed. This model comprehensively considers the transverse, vertical, longitudinal, free torsion and constrained torsional deformation of the aqueduct, as well as the influence of the fluid-solid dynamic interaction between the water body in the aqueduct and the aqueduct body. The calculation results show that the lateral dynamic interaction between fluid and tank body has a greater influence on the lateral low-frequency vibration of the aqueduct and less on the transverse high frequency. The correctness and reliability of the dynamic analysis model indicate that this model is a practical dynamic analysis model considering the fluid-structure interaction of water in the aqueduct, and the calculation results can provide a reference for the seismic design of large aqueducts.
