工程用水泥基复合材料( ECC) 与玻璃纤维增强复合材料( GFRP) 协同工作可以有效提高结构的耐久性，但关于它们在冻融循环作用下的粘结耐久性能研究较少． 通过设计 9 组共计 42 个试件，并采用快冻法研究了 75 次冻融循环后 ECC 材料与普通混凝土的质量损失率、横向相对动弹性模量及 ECC 与 GFRP 筋粘结强度的变化情况，并对试件粘结滑移曲线进行对比分析． 结果表明，ECC 材料的抗冻性能明显优于普通混凝土，同时 75次冻融循环后，强度等级为 C30 与 C50 的 ECC 与 GFRP 筋的粘结强度分别为普通 C30 混凝土与 GFRP 筋粘结强度的 3． 0 倍及 4． 3 倍; 将拉拔试验结果与目前国内外广泛应用的mBPE 模型、CMR 模型和连续曲线模型进行拟合对比，得到了 mBPE 模型及 CMR 模型相应的拟合参数和拟合相关系数，并发现 CMR 模型的拟合预测效果更好．

The combination of engineering cementitious composites ( ECC) and glass fiber reinforced composites ( GFＲP) can effectively improve the durability of structures ，but the research of bond durability between GFＲP and ECC was rarely reported under the environment of freezing-melting circulation． 42 specimens divided into 9 groups were designed herein． Quick freezing method was adopted to investigated the changes of the weight loss rate， the transverse relative dynamic modulus of elasticity of ECC，bond strength between GFＲP and ECC compared with the ordinary concrete after 75 freezing-melting circulation，and the bond-slip curves of specimens were also ana- lyzed． The results show that the antifreeze quality of ECC is superior to that of the ordinary concrete，and the bond- ing property between ECC and GFＲP bars of strength grade C30 and C50 are 3. 0 times and 4. 3 times of that ordi- nary C30 concrete and GFＲP bars respectively after 75 times freezing-melting circulation． The pull-out test results were fittingly compared with the analytical models including mBPE model，CMＲ model and continuous curve mod- el，thus the corresponding fitting parameters and fitting correlation coefficients were obtained，and the study shows that the CMＲ model provides better fitting prediction．
