本文提出一种柔性防水层上水泥混凝土桥面铺装的静力计算模型、强度条件、计算方法及修建水泥混凝土桥面铺装的建议. 北京市最近修建的城市立交桥中,柔性防水层上的水泥混凝土桥面铺装,在通车不久就发生不同程度的破碎,虽然采取了不少措施(如加单层钢筋网,或用钢纤维混凝土,或在混凝土中加塑性添加剂),但均收效甚微.这就迫使我们对这种柔性防水层上的水泥混凝土桥面铺装层的工作机理和强度条件进行了一些研究. In this paper, a static calculation model, strength conditions, calculation methods and cement concrete bridge deck pavement design of a flexible waterproof layer deck are proposed.On the recently constructed urban overpass in Beijing, the flexible waterproof layer Cement concrete pavement, in the opening soon broke down to varying degrees, although a lot of measures (such as adding a single layer of steel mesh, or steel fiber reinforced concrete, or plastic additives), but are very effective This forced us to do some research on the working mechanism and strength conditions of the cement concrete decking on this flexible waterproofing layer.
