摘　　要：对大坝内观监测仪器在工程应用中的仪器电缆、数据检验、仪器鉴定等问题进行了探讨,对内观监测差阻式仪器埋设时电缆接头工艺的改进,以及观测异常数据判别与差阻式监测仪器运行期传感器的鉴定进行了论述,并结合具体实例进行了分析。同时,强调了作为安全监测中间环节的仪器埋设安装和数据采集质量控制的重要性。Discussed are instrument cables, data verification and instrument identification of the inner differential resistance monitoring instruments applied to dam engineering, with emphasis laid on the improvement of cable joint technique for differential resistance instrument laying, the differentiation of the abnormal data, as well as the sensor identification during the operation period of the inner differential resistance-- monitoring instrument, combined with example analysis. At the same time, the importance of the instrument laying and installation and the quality control of data acquisition are stressed as the intermediate links of a safety monitoring project.
