摘　　要：对玻璃钢板加固既有混凝土梁界面应力进行了理论计算和有限元分析,研究了不同玻璃钢板长度、厚度对界面应力的影响,得到了界面应力随玻璃钢板长度、厚度变化的规律。有限元计算结果与理论结果吻合较好。The paper focuses on theory calculate and finite element analysis of the interface stress in concrete beams strengthened by gluing glass - fiber - reinforced plastic （GFRP） plates. The interface stress that is influenced by different length and thickness of GFRP is investigated. The regularity of interface stress with the differ of differ of length and thickness of GFRP plates. Comparison between FEM dates and theory datas show that resalt is satisfactory.
