摘要

结合南水北调中线工程河北段干渠左岸排水渡槽结构设计,建立了考虑流固耦合作用的上承式板拱渡槽动力分析有限元模型,研究了不同过水工况下结构的自振特性,采用反应谱法计算渡槽的地震动响应,分析了不同过水工况下渡槽主拱、槽身纵墙和纵向大梁及底板等控制截面的动应力和动位移的分布规律,为工程设计提供了计算依据。
Combined with the structural design of the roof truss-arched drainage aqueduct on the left bank of the main channel of the Mid-route of the South-to-North Water Transfer Project through Hebei Province, a FEM dynamic analysis model for the roof truss-arched equeduct is made under the consideration of the fluid-structure interaction; with which the self-vibration properties are studied under different loading conditions. The seismic responses of the aqueduct are calculated by the method of response spectrum. The analyses on the distributions of dynamic stresses and displacements of the main arch ring, the longitudinal wall of rectangular tank, the longitudinal beam and the bottom slab are made. The study lays a calculation basis for the engineering design of the project concerned.
