摘要
在室内进行了自制压力型锚固试件的锚固界面拉拔蠕变试验,用应变仪测得了试件锚固段上各监测点的实时应变,给出了锚固界面蠕变曲线及各监测位置的等时荷载—应变曲线。对曲线特征分析得到:同一监测点位置应力越大,应变越大,且应变随时间的增长逐渐增大;加载过程中锚固系统经历黏弹、黏塑和黏脱阶段后,最终沿锚固界面发生剪切拉拔破坏。
In the drawing creep test of anchorage interface of sample, the the real-time strain of the monitoring is measured on the anchoring of the pressure anchorage by strain gauge, and the creep curve of the anchorage interface and the curve of load-strain is put forward at same time. The results are as follows： the bigger stress, the bigger strain of the same monitoring, and the strain increases with time gradually; the anchorage system undergo the visco-elastic, sticky plastic and debonding stages in the process of loading, eventually it occurs along the anchoring interface.
