摘要

高强混凝土如今被广泛应用于各种重要的民用和工业建筑物上

与其维修加固相关的问题急需人们去研究、解决。目前

外贴玻璃纤维（GFRP）布加固高强混凝土的关键问题——界面的粘结破坏机理还很少有系统研究。本文对41个粘贴GFRP布的高强混凝土试件进行了单面剪切试验

得到了不同影响因素（混凝土强度、GFRP布粘结长度、宽度比、GFRP布刚度）作用下的界面剥离承载力、应变分布以及破坏模式。统计分析承载力试验值

给出了适合高强混凝土的宽度比系数

进而得到了GFRP布—高强混凝土界面的剥离承载力计算公式;进一步将试验值与陈-腾公式进行了比较

并且检验了已有承载力模型预测的准确性;由试验得到的应变数据考察了界面应变分布

发现应变的理论计算值与试验值在弹性阶段吻合较好。高强混凝土下

超过有效粘结长度后界面的破坏模式主要为界面剥离破坏。

Abstract

High strength concrete is widely used in very important civil and industrial buildings

so it is ur- gently needed to investigate and solve the problem how to maintain and strengthen these buildings.An ef- fective and popular method for strengthening existing concrete buildings is to bond GFRP on the surface of concrete.However

the interracial failure mechanism has been rarely studied especially in the case of high strength concrete.In this paper

41 single-face shear type specimens with different concrete strength

bond lengths

bond width and GFRP stiffness are tested.By analyzing the tested result

a model of bond strength which fits the result well is developed with a new width ratio coefficient and compared with Chen- Teng’s formulas.Several bond strength models available are tested to predict the bond strength between GFRP and high strength concrete.The strain profile of interface is presented and the analytical strain dis- tributions agree well with the experimental ones.
