摘要
大直径盾构隧道是建设长大穿海穿江隧道的主要建设形式,具有安全、经济、高效、智能化高等优点。纤维增强复合材料(FRP)具有轻质高强、耐腐蚀、抗疲劳及可设计等优点,在地下复杂服役环境条件下FRP可替代钢材以解决其存在的工程问题。首先,从FRP在深基坑支护结构、在基坑地下连续墙、盾构隧道内部结构以及在泥浆环流管道等4个典型大直径盾构隧道施工分部分项工程方面,介绍了国内外典型的FRP研究和应用范例,结果表明FRP力学性能和服役性能均满足地下基坑支护、盾构隧道等结构的应用要求。针对研发现状及当下应用存在的问题,对FRP在地下工程结构中的应用前景做出展望。
Large diameter shield tunnel is the main construction form of long and large tunnels that cross sea and river,which has the advantages of safety,economy,efficiency,and intelligence.Fiber Reinforced Polymer(FRP)possess the advantages of light weight,high strength,corrosion resistance,fatigue resistance and design-ability,which can be used to replace steel to address engineering problems in complex underground service environments.The research and applications of FRP at home and abroad were presented from four typical projects of large-diameter shield tunnel construction,such as deep foundation excavation supporting structure,underground diaphragm wall,shield tunnel internal structure,and mud circulation pipe.The results showed that the mechanical and service properties of FRP could meet the requirements in the application of underground foundation excavation supportings,shield tunnels and other structures.Finally,the application of FRP materials in the underground engineering structures was prospected according to the research and application states and current problems of FRP.
