为构造质量的评估和设计工程的水管理和水力发出的电力的设计的确认，并且特别为水坝安全操作行为的控制，监视传感器的安全在设计工程的一个多数被采用。这些传感器被用来在水坝构造和操作时期期间监视工程，并且在水库安全操作和生产好处起一个重要作用。与变化操作工程的环境和运行时刻，有一些因素，影响工程的操作和管理，例如测量数据的损坏传感器和不稳定性的某个数量。因此，评估是迫切的存在在水管理和水力发出的电力工程监视传感器的安全投射。然而，目前有既不标准也不评估指南。基于设计实践，这研究为监视传感器的安全的评估检验了一些关键技术包括监视系统的安全的评估过程，设备，微分电阻器传感器和颤动的电线的二典型的片的所在地的察觉方法传感器，通讯电缆线差错的所在地的察觉方法，和传感器的有效性测试测量了数据。这些关键技术在 Xiaolangdi 水控制工程和 Xiaoxi 水力发出的电力工程被使用。结果证明传感器的一个多数的测量数据可靠、合理，并且能相当在操作过程的工程反映结构的变化行为，显示监视二个工程的传感器的安全的可获得性高。

英文摘要：

For the evaluation of construction quality and the verification of the design of water conservancy and hydropower engineering projects, and especially for the control of dam safety operation behavior, safety monitoring sensors are employed in a majority of engineering projects. These sensors are used to monitor the project during the dam construction and operation periods, and play an important role in reservoir safety operation and producing benefits. With the changing of operating environments and run-time of projects, there are some factors affecting the operation and management of projects, such as a certain amount of damaged sensors and instability of the measured data. Therefore, it is urgent to evaluate existing safety monitoring sensors in water conservancy and hydropower engineering projects. However, there are neither standards nor evaluation guidelines at present. Based on engineering practice, this study examined some key techniques for the evaluation of safety monitoring sensors, including the evaluation process of the safety monitoring system, on-site detection methods of two typical pieces of equipment, the differential resistor sensor and vibrating wire sensor, the on-site detection methods of communication cable faults, and a validity test of the sensor measured data. These key techniques were applied in the Xiaolangdi Water Control Project and Xiaoxi Hydropower Project. The results show that the measured data of a majority of sensors are reliable and reasonable, and can reasonably reflect the structural change behavior in the project operating process, indicating that the availabilities of the safety monitoring sensors of the two projects are high
