摘　　要：本文介绍了碳纤维增强塑料的加固机理,指出有必要确定粘结长度及粘结长度内碳纤维应变分布,提出了描述粘结长度内碳纤维、环氧树脂及混凝土三者间关系的力学模型,并推导出了计算粘结长度以及碳纤维应变分布的公式。This text introduce carbon fibre reinforcement mechanism of reinforced plastics, point out necessary to is it glue length of forming and is it form length the carbon fibre meets an emergency and is distributed to glue to confirm, have proposed describing that glues and forms the mechanics model of the relation among carbon fibre , epoxy resin and three of concrete in the length, is it is it is it is it form length and carbon fibre meet an emergency the formula distributed to glue to calculate to appear to derive.
