三层地铁车站振动台试验的数值模拟
|
摘要
进行了三层地铁车站大型振动台试验,获得了可靠的试验数据。通过室内实验获取了模型材料和土体材料的力学参数。基于ABAQUS有限元计算平台,建立了振动台试验的二维有限元模型,处理了混凝土本构模型及其参数的选取、土体本构模型及其参数的选取、阻尼设置、边界条件设置等问题。对多种工况下的试验结果和模拟结果进行了对比分析。结果表明,按照本文建议的建模方法,可以很好地重现振动台试验,数值模拟结果无论在趋势上还是数值上都和试验结果符合得很好。
A large-scale shaking table test of three-story subway station has been performed,and some reliable testing data are acquired.The model and soil material mechanical parameters are achieved through indoor experiments.Based on ABAQUS FEM calculation platform,two-dimensional FEM model of the shaking table test is constructed.Problems such as concrete constitutive model and its parameters,soil constitutive and its parameters,damping settings,and boundary condition settings are handled.Comparative analysis is performed between testing data and simulation data.The results show that: The FEM model could closely simulate shaking table test if we construct the model following the method recommended in this paper.The numerical data accord well with the testing data both in trend and magnitude.
