依托长沙市某分布式屋面光伏发电项目,现场测试了18个环氧树脂工程胶粘结基础的抗拔性能,对基础位移-荷载变化规律进行分析。结果表明,未破坏的粘结基础位移-荷载变化有明显的弹性阶段;粘结基础产生位移时所对应的临界荷载越大,其基础抗拔承载力越高;粘结基础在环氧胶-屋顶面层界面均存在不同程度脱空现象,更易产生应力集中,导致基础破坏。与传统的混凝土支墩基础相比,粘结基础的抗拔承载力更高,但施工工艺要求也较高,以此确保其粘结性能。

Based on a distributed roof photovoltaic power generation project of Changsha,the pull-out performance of 18 epoxy resin adhesive bond foundation was tested at site,the foundation displacement-load change rule was analyzed. The analysis results show that there is an obvious elastic phase of the unpulled adhesive base displacement-load change. The higher the critical load corresponding to the initial displacement of the bond foundation,the higher the foundation pullout bearing capacity. The adhesion foundation in the epoxy resin adhesive-roof surface layer has different degrees of clearance phe...
