一种PCCP管预应力碳纤维补强加固结构设计
摘要：
本发明涉及一种PCCP管的预应力碳纤维补强加固结构设计，所述PCCP管预应力碳纤维补强加固结构从内侧到外侧依次包括：柔性防渗涂层、碳纤维布层、弹性及刚性组合垫层以及PCCP管（预应力钢筒混凝土管）。本发明提供的PCCP管预应力碳纤维补强加固结构，通过设置弹性垫层，在保证PCCP管没有明显受力的前提下，增加了碳纤维布层的变形量，从而增加了碳纤维布层所能承受的拉应力，即预应力碳纤维，进而减小了分散到PCCP管的应力，避免了PCCP管混凝土出现裂缝或预应力钢丝断裂，使碳纤维材料的高强度优势得到充分发挥，最大程度地增加了碳纤维对PCCP管的补强加固效果。
摘要（英）：

The invention relates to a prestressed carbon fiber reinforced structure design of a prestressed concrete cylinder pipe (PCCP). A prestressed carbon fiber reinforced structure of the PCCP sequentially comprises a flexible impermeable coating, a carbon fiber cloth layer, an elastic and rigid compound cushion layer and the PCCP from inside to outside. According to the prestressed carbon fiber reinforced structure of the PCCP, by arrangement of an elastic cushion layer, on the premise of guaranteeing that the PCCP is not stressed obviously, the deformation of the carbon fiber cloth layer is increased, so that pulling stress capable of being born by the carbon fiber cloth layer, namely prestressed carbon fibers, is increased, the stress dispersed to the PCCP is reduced, fracture of PCCP concrete or breakage of a prestressed wire is avoided, the high strength advantages of the carbon fiber material is brought into full play, and the PCCP reinforcing effect of carbon fibers is increased to the largest extent.
