| 摘 要： | 在表面嵌固法中，嵌固板条能否发挥其抗拉能力的关键，在于嵌固板条与混凝土表层是否具有足够的粘结强度。通过研究嵌固板条与混凝土基体的粘结强度和破坏情况，得到破坏形态均为嵌固材料从结构胶层拔脱，发生滑移破坏，造成粘结失效。粘结强度主要与结构胶自身的粘结强度和嵌固材料表面的粗糙程度有关，基材混凝土的强度对粘结强度的影响不大，说明嵌固板条施工时应完全埋入混凝土的表层，以减小嵌固板条剪应力的梯度变化，使之受力更趋均匀，可为采用表面嵌固法时嵌固板条的锚固长度设计提供一定的参考。 |

| Abstract: | when using Near-surface Mounted,it is the key that sufficient bond strength between the tensile material and concrete.In this paper,test method is used to study the bond strength and destruction with Near-surface Mounted(NSM) in concrete structure,a reference is also provided to determine the tension anchorage length when using NSM.The failure mode in this experiment is that the tensile material were pull off from the Structural adhesives,sliding failure occurred,causing bonding failure.Adhesive bond streng... |
| Keywords: | concrete structure Near-surface Mounted bond strength anchorage length |
