| 摘 要： | 了解锚索应力状态时,锚力计示值与千斤顶示值之间普遍存在着较严重的不匹配现象,通过室内外试验和工程数据分析的汇总分析,得到这种不匹配现象主要由仪器设备使用错误及数据错误、测量仪器误差、构件误差及安装误差等施工误差、锚索张拉及锁定时应力损失等原因造成。把千斤顶示值和锚力计示值有机结合,通过现场试验建立两者示值之间的对应关系,能够对锚索的真实应力状况有个较为全面的、准确的了解。

| Abstract: | Indicating value of dynamometer usually mismatches with that of lifting jack.Through the indoor and outdoor test and the analysis of engineering statistics,The reasons including errors of apparatuses,data,measure,frame member,assembling,and stress loss during stretching and locking of anchor,etc,are got.By applying dynamometer and jack together and founding the relation of indicating value,the stress of anchors could be analyzed more completely and accurately. |
