摘要：许多水利水电工程均使用安全检测传感器来评估施工质量和验证设计，尤其是控制大坝的安全运行。这些传感器用于大坝施工和运行期间的监测，在水库安全运行和保证生产效益方面发挥着重要作用。随着项目运行环境和运行时间的改变，存在一些影响项目运行和管理的因素，例如，一定数量损坏的传感器和测量数据的不稳定性。因此，在水利水电工程中迫切需要对现有的安全检测传感器进行评估。但是目前没有现成的标准和评估手册。基于工程实践，本文研究了一些安全监测传感器评估的关键技术，包括安全监测系统的评估过程、两种典型设备(微分电阻传感器和振弦式传感器)的现场检测方法、通信电缆故障的现场检测方法和传感器测量数据的有效性试验。这些关键技术被应用于小浪底枢纽工程和小溪水电站工程。结果表明：传感器测量的大部分数据是可靠合理的，并可以合理反映工程运行过程中结构的改变行为，表明两个工程的安全检测传感器的可行性非常高。

Abstract：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.
