摘要:
采用20结点空间块体单元剖分渡槽槽身和槽墩,分别用耦合自由度、低刚度块体单元、多个弹簧单元模拟槽身横向拉杆和加劲肋、渡槽槽内水体及盆式橡胶支座,建立大型双槽渡槽结构动力分析的有限元模型,并对南水北调水利工程某大型双槽渡槽进行了多工况动力特性分析,探讨了渡槽横向拉杆、槽内水体及盆式橡胶支座等多种因素对渡槽整体动力性能的影响.计算结果表明,渡槽横向拉杆对渡槽的横向动力特性影响不可忽略,盆式橡胶支座竖向刚度在一定范围内影响渡槽的动力特性,槽内水位的高低及分布情况对渡槽的动力特性影响很大.
Abstract:
The 20-node space block unit was used to divide the aqueduct body and the trough pier, and the coupling degree of freedom, low stiffness block unit and multiple spring units were used to simulate the lateral tie rod and stiffener of the trough body, the water body in the aqueduct and the basin rubber support, and the finite element model of the dynamic analysis of the structure of the large double-trough aqueduct was established, and the dynamic characteristics of a large double-trough aqueduct of the South-to-North Water Diversion Project were analyzed under multiple working conditions, and the influence of various factors such as the transverse tie rod of the aqueduct, the water body in the trough and the basin-type rubber support on the overall dynamic performance of the aqueduct was discussed. The calculation results show that the influence of the transverse tie rod of the aqueduct on the transverse dynamic characteristics of the aqueduct cannot be ignored, the vertical stiffness of the basin rubber support affects the dynamic characteristics of the aqueduct within a certain range, and the water level and distribution in the aqueduct have a great influence on the dynamic characteristics of the aqueduct.
