摘　　要：玄武岩纤维混凝土路面板在其受力上受各种参数的影响,运用有限元计算法研究其路面板结构参数敏感性分析,得出:提高土基强度或者提高底基层下路面结构的强度对降低水泥混凝土的应力和竖向变形是十分有利的;降低水泥混凝土面层模量的同时保持水泥混凝土的强度,对水泥路面板的受力是十分有利的。Basalt fiber concrete pavement plate was affected by various parameters on the stress. This paper used the finite element method to study the pavement plate structure parameters sensitivity. It obtained that improving the subgrade strength or the subbase pavement structure strength was very favorable to reducing the cement concrete stress and vertical deformation. It also proved that reducing the cement concrete surface layer modulus while maintaining cement concrete strength were very favorable to the concrete pavement plate on the stress.
