摘　　要：为了准确分析水泥混凝土路面接缝填缝料的受力状态,基于粘弹试验测定了橡胶沥青填缝料的松弛蠕变曲线与松弛模量曲线,通过非线性拟合方法求得有限元软件ANSYS中用于描述粘弹类材料粘弹性质的广义Maxwell模型和Prony级数的两种表达方式所需的参数。并结合粘弹性材料时温等效性质,回归了主曲线函数力学参数,为建立接缝有限元动态分析模型,研究移动荷载与温度荷载作用下此类型水泥路面接缝填缝料的粘弹性力学响应分析提供了方法和基础。In order to accurately analyze the stress state of joint filler for cement concrete pavement,the relaxation creep curve and relaxation modulus curve of asphalt rubber joint filler were measured based on viscoelastic test,and nonlinear fitting methods were utilized to obtain the parameters required for the generalized Maxwell model and the Prony series,which are used in the finite element software ANSYS to describe the viscoelastic properties of materials.Combined with the time temperature equivalent property of viscoelastic materials,the mechanical parameters of the principal curve function are regressed,which provides a method and basis for establishing the finite element dynamic analysis model of joints and studying the viscoelastic mechanical response analysis of this type of cement pavement joint filler under moving load and temperature load.
