连续纤维增强材料（CFRM）作为一种新型的高性能混凝土结构增强或预应力材料，受到了广泛的关注。本文主要研究了碳纤维、芳纶纤维和玻璃纤维三种纤维的碳纤维水泥混凝土抗拉强度的变化规律，确定碳纤维水泥混凝土特征强度所需试件数量，碳纤维水泥混凝土弹性模量与应力水平的关系，碳纤维水泥混凝土的粘结性能，2）研究了CFRM主筋混凝土梁的极限弯矩、CFRM主筋混凝土梁和有、无CFRM抗剪筋混凝土梁的极限剪力以及预应力CFRM筋混凝土梁的极限剪力; 3）CFRM筋混凝土梁的最小主筋数，4）研究了CFRP加固梁的挠度和裂缝宽度; 5）研究了CFRP体外预应力混凝土、CFRP体外预应力加固受损钢筋混凝土和CFRP化学预应力混凝土。

Continuous fiber reinforcing materials(CFRM) are given attension as a new highquality reinforcing orprestressing material for concrete structures. The purpose of this study was to establish design procedures for concrete structures with CFRM.The main results were obtained from the following investigations.1) Variation properties of tensile strength of CFRM of carbon, aramid and glass fibers, neccessary number of specimens to determine the characteristic strength of CFRM, relation between elastic moduli of CFRM and stress levels, bond properties of CFRM, and creep properties of CFRM were investigated.2) Ultimate moment of concrete beams with CFRM main reinforcement, ultimate shear force of beams with CFRM main reinforcement and with or without CFRM shear reinforcement, and ultimate shear force of prestressed concrete beams with CFRM tendon were investigated.3) Minimum main reinforcement of beams with CFRM, and improvement of ductility and capacity of moment redistribution of beams by confinement of concrete with CFRM were investigated.4) Deflection and crack width of beams with CFRM were investigated.5) Prestressed concrete with CFRM external cable, strengthening of damaged reinforced concrete by prestressing with CFRM external cable, and chemically prestressed concrete with CFRM were investigated.
