平面交叉口水泥混凝土路面板块划分方法

Division method for slab of cement concrete pavement at intersection

针对平面交叉口水泥混凝土路面接缝设计复杂和没有成熟的板块划分方法的问题,提出了平面交叉口水泥混凝土路面板块划分的四种基本方法:逼近法、圆心法、残余法和修补法。并以环道外缘石为直线圆角形的四路环形交叉口为例,介绍了板块划分四种基本方法的具体应用。实践表明,平面交叉口水泥混凝土路面的板块划分通过以上三种或四种基本方法的有机结合就可以实现板块划分的自动化,大大提高平面交叉口CAD系统的适应性和设计效率。

This paper put forward four basic methods including approach method, center method, residue method, and patch method for dividing slab and took fourlegs roundabout intersection with the shape of linearc curbs as an example for explaining concrete application of those methods. The practice indicates that the automatic design of dividing slab can be developed by integrated application of the three or four basic methods, so it improves the adaptability of Intersection CAD System and raises the design efficiency.
