超载对水泥混凝土路面力学响应的有限元分析

The finite element analysis of mechanical response of overload on cement concrete pavement

用三维有限元接触模型研究了超载对水泥混凝土路面力学响应的影响,并据此分析了其对混凝土路面使用寿命的影响,结果表明:随超载率的增加,水泥混凝土路面结构的力学响应值大幅增加,而路面结构的使用寿命大幅缩短。

The overload influence on mechanical response of cement concrete pavement was studied with three dimensional finite element contact model and its influence on concrete pavement service life was analyzed. The result indicated that mechanical response value of cement concrete pavement increased wide range with overloading ration increasing, while the service life of pavement structure shortened wide range.
