摘要:
根据可液化土层上土-地铁隧道结构动力相互作用大型振动台模型试验结果,以软件ABAQUS为平台,将地基土-地铁隧道结构体系视为平面应变问题,采用记忆型嵌套面粘塑性动力本构模型和动塑性损伤模型分别模拟土体和隧道结构混凝土的动力特性,建立了土-地铁区间隧道非线性动力相互作用的有限元分析模型。对各种试验工况下地基土-地铁隧道结构体系的地震反应进行了数值模拟,并与试验结果进行了对比。结果表明:数值模拟与振动台模型试验结果基本一致,呈现出相似的规律性,相互验证了基于ABAQUS软件的力学建模和振动台试验结果的正确性。
Abstract:
Based on the results of the large-size shaking table test of subway tunnel built in liquefiable site,by using ABAQUS software and considering the influence of soil-structure interaction for 2D finite element analysis,the nonlinear dynamic in teraction of soil-subway tunnelwasmodeled.In the modeling,dynamic visco-plastic memorial nested yield surface model was used to model dynamic characteristics of soils,and dynamic plastic-damage model was used to model dynamic characteristics of tunnel concrete.The seismic response of soil and subway tunnel system under different test conditions was analyzed by the numerical simulation method.And then,the smiulation results and the shaking table test records were compared in detail in this paper.The results show that the smiulation results of seismic response are basically identical with the shaking table test records.So that,the modeling analysis based on software ABAQUS and the shaking table test results are proved to be correct.
