Bearing Capacity of CFRP-Lined PCCP Under Internal Pressure

  • 摘要: 在内压作用下,预应力钢筒混凝土管(PCCP)可能发生各结构层失效。在PCCP内壁粘贴碳纤维增强复合材料(CFRP)是常见的修复方法,然而修复PCCP在内压作用下的结构失效机理研究尚不成熟。鉴于此,建立了CFRP内衬加固PCCP在内压作用下的多层圆环模型(MRM)力学模型,推导得到了CFRP内衬加固PCCP在内压作用下管壁径向位移、应力和应变的表达式。该力学模型计算结果与已有试验结果吻合良好,验证了力学模型的正确性。参数分析结果表明:增加钢筒厚度和混凝土管芯厚度可提高PCCP的内压承载力,提升预应力水平可提高PCCP抗开裂能力,增加CFRP厚度可以提高CFRP内衬加固PCCP的内压承载力。
