【摘要】 为了能够简便快捷地估算渡槽结构横槽向地震响应,以Housner弹簧-质量简化模型及土-桩非线性动力Winkler地基梁简化模型为基础,建立了一种可以同时考虑流-固耦合动力相互作用与土-桩非线性动力相互作用的渡槽结构横槽向抗震简化计算模型。在此基础上,应用此简化计算模型对渡槽拟动力试验模型在三种试验地震波作用下的横槽向地震响应进行了计算,并将计算结果与拟动力模型试验结果进行了对比,验证了本文建立的简化计算模型的合理性。更多还原

【Abstract】 In order to simply and fastly estimate the transverse seismic responses of the aqueduct structure system,an aseismic simplified calculation model was proposed in this paper,in consideration of the fluid-structure coupling dynamic interaction with the Housner spring-mass simplified model and the nonlinear soil-pile dynamic interaction with the soil-pile nonlinear dynamic Winkler foundation beam simplified model. On this foundation,the transverse seismic responses of the pseudo-dynamic test model were calculated under the action of three kinds of test seismic waves,which adopted the simplified calculation model. Compared with the pseudo-dynamic test results,the rationality of simplified calculation model of aqueduct structure was verified.更多还原
