摘 要:为准确研究渡槽的地震动力响应,本文以庄浪河渡槽为研究对象,基于FSI系统,建立了槽体-水-槽墩-基础的精细数值模型,以此求解了4种通水条件下渡槽地震响应特性,计算了庄浪河渡槽在天津宁河地震波作用下的动力响应。计算结果表明,基于FSI压力-位移有限元格式能够有效考虑槽体与水的相互作用;水位深度是影响渡槽动力响应的关键因素;渡槽抗震设计时需考虑动水压力的影响。研究成果可以为渡槽抗震设计提供科学参考和依据。The seismic dynamic response of the Zhuanglang River aqueduct is studied.This study has established the simulation model with the aqueduct,water,and pier foundation based on the FSI system.Four kinds of water conditions have been solved.The dynamic response characteristics of the aqueduct trough were simulated.The calculation results show that the FSI-based pressure-displacement finite element scheme can effectively deal with the interaction between the aqueduct and the water;the water depth is a key factor affecting the dynamic response of the aqueduct;the influence of the dynamic water pressure should be considered in the aqueduct seismic design.The research results can provide some scientific references for the seismic design of the aqueduct.
