摘要
选取ANSYS有限元分析软件为手段,对水泥混凝土路面在移动荷载作用下的应力应变情况进行了分析.分析结果表明在不同车速所产生的移动载荷作用下面层的竖向位移和板底拉应力有所差别,在车速较低的时候荷载对水泥路面的影响要比车速较高时更为明显.验证了使用ANSYS软件进行水泥混凝土路面结构分析的可行性,分析结果对路面结构设计提供了一些指导.
The paper picks ANSYS which is finite element analysis software as method, analyzes stress and strain of cement concrete pavement under the affection of moving load. Analysis results show that the vertical displacement and pulling stress on bottom of road surface are different under the affection of moving load which results from different vehicle speed, the affection which results from slower vehicle speed and affect on cement concrete pavement is greater than faster vehicle speed. This paper verifies the feasibility of cement concrete pavement structure analysis base on ANSYS software. Analysis results provide some guidance to structural design of pavements.
