| 摘 要： | 基于试验研究资料的分析,对于大型泵站中具有合适锚固的CFRP片材加固受弯构件变形计算方法进行研究,认为加固梁的弯矩-曲率曲线符合三线型规律（混凝土开裂前,混凝土开裂后,受拉钢筋屈服后）.通过解析分析,得到试验梁在通常两点加载条件下的任一加载阶段的弯矩及变形计算公式,与相应条件试验梁的试验测试结果吻合,可为泵站工程设计规程的制定提供参考。

| Abstract: | The present work is intended to develop a simplified calculation based on the test data. It is known that the regular pattern of the strengthened section response is trilinear. Closed form equations are developed for the deflection calculation throughout the load range. The formula has a higher precision after verifying by the test date. |
