| 摘 要： | 针对34组后植筋和6组预埋钢筋组成的共120个混凝土植筋试样进行了室内拉拔试验,综合对比分析表明钢筋直径、混凝土强度、锚固长度和植筋孔径是影响钢筋平均极限拉拔力与胶-混界面极限平均粘结力的重要因素;混凝土预埋筋和后植筋中钢筋平均极限拉拔力无显著变化,表明采用后植筋补强混凝土强度可以实现与预先埋设钢筋相同的效果;混凝土植筋试件主要表现出钢筋拉断、胶-混界面破坏和混凝土劈裂等三种破坏形式,并基于理论分析推导获得试件拉拔试验中出现试件劈裂破坏时钢筋极限拉拔承载力计算公式. |

| Abstract: | Based on 120 specimens of installed bar consisting of 34-group for specimen of post-installed bar and 6-group for specimen of embedded bar,comparative analysis considering diameter of steel bar,tensile strength of concrete,anchoring depth of steel bar,hole diameter and styles of installing bar are carried out under a series of pull-out tests.The experimentally measured results have shown that the bonding properties of post-installed bar are significantly influenced by above mentioned factors.The tests resul... |
