摘要
针对重载交通对水泥混凝土路面的破坏,在水泥混凝土面板间设置传力杆,利用有限元软件分析接缝传力杆对水泥混凝土路面的应力和位移的影响。结果表明:设置传力杆可以有效减少受力面板的应力和位移变形,同时,将受力面板所承受的应力和位移变形传递给相邻的不受力面板,使水泥混凝土路面的受力和位移变形更加均匀,提高重载水泥混凝土路面的使用寿命。
In view of the overload transportation damage to the cement concrete pavement,dowel bars were set between cement concrete slabs,the impact of stress and displacement on dowel bars in cement concrete pavement was analyzed by the finite element software. The experimental results show that setup of the dowel bars can effectively reduce the stress and displacement of stressed panel,meanwhile,the stress and displacement of stressed panel are passed to adjacent not-stressed panel,the stress and displacement of cement concrete pavement are more evenly,and the service life of heavy-load cement concrete pavement increases.
