| 摘 要： | 在现有的纤维增强复合(FRP)材料片材的锚固技术基础上,开发出一套基于FRP材料的波形锚和相应的锚具系统.针对特定的FRP片材,设计并制作了典型的锚具样品,利用该系统在实验室进行张拉试验.试验结果表明:FRP片材破坏时,单层材料比双层的强度利用率高,FRP波形锚能正常工作,片材中的受力不均匀问题是影响和制约锚固体系的主要因素.针对实验中出现的受力不均匀问题,改进了张拉装置,且在FRP片材张拉前每隔一段距离进行涂胶固化,改进后的系统成功应用于加固工程中.

| Abstract: | On the basis of the anchorage technology for pre-stressed FRP(fiber reinforced polymer) sheets,a wave-shaped anchor made of FRP material and corresponding anchorage system were proposed.For specific FRP sheets, a set of anchorage device was designed and made.In addition,tension tests were conducted on FRP sheets with this system.The testing indicates that single-layer sheets were more effective than twin-layer when FRP sheets were destroyed, and the FRP wave-shaped anchor may work well.The main factor affec... |
