摘要
众所周知预应力混凝土路面能够很好的解决混凝土路面的开裂问题,但是,如何对其施加预应力却无从下手,这样我们提出了斜向布置钢筋来防止水泥混凝土路面开裂,为了研究斜向布置钢筋在防止水泥混凝土路面裂缝中的应用效果,在进行大量试验研究的基础上提出了混凝土应力补偿止裂机理的理论和方法。在混凝土中布置斜向的钢筋,能够使路面在温缩时,横向变形补偿纵向变形的需要,达到止裂的目的。
As everyone knows, the prestressed concrete pavement is enabled to better solve crack of concrete pavement. Howerev for how prestressing it, we have no way. This way, we put forward the oblique arrangement of reinforcements to avert crack of concrete pavement. So as to improve applied effects doing that,on the basis of large numbers of tests, we pose the theory and methods for mechanism of preventing the crack by concrete prestressing compensation. Oblique arrangement of reinforcement in concrete could make the transverse deformation compensate longitudinal one as the temp contraction is appearing on pavement, achieving the goal to avert crack.
