化学植筋技术是一种基于混凝土结构的新型后锚固技术,但目前对动力荷载下的植筋受力情况研究较少。综合国内外对化学植筋在静力作用下的黏结机理,对植筋试件在低周循环荷载作用下的黏结性能进行试验研究。通过4个混凝土试件的植筋在低周循环荷载作用下的黏结性能试验,得到植筋的位移-荷载及应变-荷载等滞回曲线、植筋轴向应变及黏结应力曲线等并对此进行分析,得出一些植筋在动荷载作用下黏结性能相关的结论。
Chemical planting bar technology is a new type of post-anchoring technology based on concrete structure. However, there are few researches on anchorage force under dynamic load. Based on the bonding mechanism of chemical planting bar under static force both at home and abroad, the bonding performance of bar-embedded specimens under low cyclic loading was studied. Through the test of bonding performance of four concrete specimens under low cyclic load, the displacement-load and strain-load hysteresis curve of planting bar, the axial strain of anchorage bar and the bond stress curve are obtained The analysis results show that some of the planting tendons under the action of dynamic load bonding performance-related conclusions.
