| 摘 要： | 预留试件拉拔法检测喷射混凝土与围岩粘结强度,存在挖环形槽难度大、埋拉杆难以保证不偏心等同题,为此提出改进建议,既不用挖环形槽、又不埋拉杆.采用改进方法于2007年3月进行了现场试验并获得成功.该检测方法对预留试件没有扰动和损伤,所测粘结强度能真实反映喷射混凝土与围岩的粘结情况.该方法可供有关规骀范修订时参考.

| Abstract: | The beforhand saving sample pull-out method check measurement bond strength of shotcrete and adjoining rock, the method exist that diging annulan trough is difficulty and burying draw bar difficultly assure no off-centre. The paper presented improving suggestion, it is not diging annulan trough and not burying draw bar, scene test of improving method gained success in March 2007. The check measurement method not disturb and damnitg befohand saving sample, checking bond strength really can reflect bond condition of shotcrete and adjoining rock. |
