连续配筋混凝土路面设计施工技术研究

Research on Design and Construction Technology of Continuously Reinforced Concrete Pavement

工业园区内城市道路建设中多采取水泥混凝土路面结构,这有助于避免沥青路面开裂、车辙、坑槽等病害。普通水泥混凝土路面接缝数量多,极容易造成路面结构水损害,连续配筋混凝土路面(CRCP)则是在普通水泥混凝土中设置纵向螺纹配筋,避免混凝土路面收缩裂缝的产生。文章依托浙江省宁波市北仑柴桥临港产业园区纬中路水泥混凝土路面开展双层连续配筋混凝土路面结构设计,并且采取ABQUES有限元对车辆荷载作用下水泥混凝土板不同施工参数下的力学响应进行分析,以便为相关类似工程建设提供理论参考。

Cement concrete pavement structure is often adopted in urban road construction in industrial parks,which helps to avoid diseases such as asphalt pavement cracking,rutting,potholes.There are many joints in ordinary cement concrete pavement,which is very easy to cause water damage to pavement structure.Continuously reinforced concrete pavement(CRCP)is to set longitudinal threaded reinforcement in ordinary cement concrete to avoid shrinkage cracks in concrete pavement.Based on the cement concrete pavement of Weizhong Road in Beilun Chaiqiao Lingang Industrial Park,Ningbo City,Zhejiang Province,this paper carries out the structural design of double-layer continuously reinforced concrete pavement,and adopts ABQUES finite element to analyze the mechanical response of cement concrete slab under different construction parameters under vehicle load,so as to provide theoretical reference for similar engineering construction.
