混凝土大坝中差阻式监测仪器的编号识别

Design number discrimination of differential resistance instruments for concrete dam

根据差阻式电测仪器及其测量系统的原理,并结合其埋设的具体部位、埋设前的率定资料、仪器鉴定资料、电缆电阻、仪器绝缘性能、仪器类型、历史测量数据等指标,提出了辨识仪器编号的方法.在安康水电站部分仪器因电缆盗割后重新恢复观测的应用表明,使用该方法辨识成功率达88%～93%,保证了监测资料的连续性和可靠性.

The design number of differential resistance instruments in the concrete dam is unique, but lots of instrument numbers are difficult to discern as a result of deformation so that the original observational data of the instruments are not reliable and not accurate. In this paper, the method of differential resistance instrument discrimination is proposed in accordance with the principle of the instrument and its type, the position of the instrument, the original observational data of the instrument, the appraised data and the historical data of the instrument and the cable resistance and the insulation capability of the instru- ment. The method is applied in Ankangconcrete dam and the rate of success comes up to 88%-93%.
