摘　　要：文章介绍了面板堆石坝面板挠度监测的技术方法,并对其中三种技术方案优缺点进行比较,提出监测仪器表面安装与内部安装的差异及可能存在的问题。重点介绍了单点测斜仪(电平器)的技术特点及安装埋设方法。结合德泽水库枢纽工程面板堆石坝挠度监测的实际应用,采用单点测斜仪(电平器)及在面板内部安装的技术方案,通过安装埋设及观测数据整编分析,验证了该技术方案和安装埋设方法的合理性和可行性,具有施工干扰小、能真实反映面板变形状态、不影响面板表面观感、方便观测及运行维护等优点。The technical methods of deflection monitoring for slabs of CFRD are introduced in the paper. Based on the comparison of the three technical methods, differences and possible problems of monitoring instruments installed inside or outside slabs are raised. This paper focuses on the technical characteristics and installation methods of the single point inclinometer （electro-levels）. It was installed inside the slabs of DeZe CFRD. It is verified that the scheme and the method of the single point inclinometer （electro-levels） are reasonable and feasible by installation and data analysis. The scheme has several advantages such as small disturbance, accurate observation, convenient observation and convenient maintenance.
