摘要(Abstract)：

【目的】水利水电工程安全监测领域尚未系统地开展监测仪器服役完好率分析。为深入分析我国水利水电工程安全监测仪器服役完好率特性，并为监测设计、仪器选型和更新维护等提供科学依据，【方法】收集了我国12个典型水利水电工程的安全监测仪器服役表现的大样本数据，通过统计分析、相关性分析与配对样本T检验方法，统计了各工程安全监测仪器的完好率，分析了整体完好率与服役时长间的相关性，检验了主要监测项目监测仪器完好率差异性，以及主要监测量差阻与弦式监测仪器完好率差异性。【结果】结果显示：仪器服役总年数与整体完好率之间的相关系数绝对值为0.65,主要监测项目监测仪器完好率之间的差异显著性水平为0.049,主要监测量差阻与弦式仪器完好率分别是78.87%与85.36%,主要监测量差阻与弦式仪器完好率之间的差异显著性水平为0.298。【结论】结果表明：水利水电工程安全监测仪器整体完好率与运行总年数呈中等程度的线性相关关系；主要监测项目监测仪器完好率表现存在差异，渗流渗压监测仪器完好率明显高于应力应变及温度监测仪器完好率；主要监测量差阻与弦式监测仪器完好率表现不存在显著差异，振弦式仪器完好率表现略高于差阻式仪器完好率。
