摘要
预应力CFRP加筋土技术是一种新型的加筋土技术。这项技术充分地利用了CFRP材料的高强度、高弹性模量、耐腐蚀性、轻质等优点 ,应用该技术施工的加筋土工程具有变形小、强度高、施工速度快的特点。应用三轴试验研究了CFRP材料加筋中砂、粘土试件的应力应变关系 ,提出了伪粘聚力的概念 。
As a new reinforced earth technology, CFRP prestressed reinforced earth fully utilizes the advantages of CFRP, such as high strength, high modulus of elasticity, anti corrosion and light weight. Reinforced earth structures using CFRP technology have the characteristics of small deformation, high strength and speedy construction. In this paper the stress-strain relationship of clay and sand specimens with CFRP strips is studied by means of triaxial testing. A concept of fictitious cohesion strength is proposed, which can successfully explain the principles of CFRP prestressed reinforced earth technology.
