中文摘要:

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.

英文摘要:

Based on the principle of the electrothermal effect and the piezo-electric effect of carbon fiber reinforced concrete (CFRC), the properties of continuous beam britdges mounted withg CFRC (The number of spans is from 2 to 4) are ivestigated in this study, the thin CFRC layers were first mounted into the lower edge (or the upper edge) of a continuous beam bridge, and embed electrodes in a smaller distance part from the support of each span for enhancing the electrical conductivity. Aimed at the extrusive situation of overloading, the specified CFRC layers were electrified automatically, and correspondingly the temperature was increased, the load capacity and deformation resistance of the intelligent bridge can be enhanced. Research shows: the load capacity and the deformation resistance of continuous beam bridges with CFRC layers are improved significantly.
