基于碳纤维混凝土的电热效应、电力效应原理,着重研究碳纤维混凝土两跨至四跨连续梁,在连续梁的下缘(或上缘)布置短切碳纤维混凝土薄层,并在其相应跨度两端设置电极,以利通电;针对超载突出情况,给碳纤维混凝土智能化通电、加温,以提高桥梁的承载能力和变形能力.研究表明:碳纤维混凝土连续梁的承载能力和变形能力都得到大幅提高. Based on the electric and thermal effects of carbon fiber reinforced concrete and the principle of power effect, the paper focuses on two-span to four-span continuous beams of carbon fiber reinforced concrete (CFST), and arranges thin layers of chopped CFST at the lower edge (or top edge) of continuous beams Electrode for the benefit of energization.According to the situation of overloading, the carbon fiber concrete is intelligently energized and warmed to improve the carrying capacity and deformation capacity of the bridge.The results show that the carrying capacity and deformation capacity of carbon fiber reinforced concrete continuous girder have been greatly improved.
