摘　　要：位移监测及分析是大坝安全监测的重点内容 ,垂线是使用最普遍的位移监测手段之一 ,它具有测点多、深入坝体等特点 ,获得的监测数据包含了反映坝体安全状态的信息。为更好地分析这些信息 ,在已有的监测分析方法基础上 ,结合近期研究成果 ,阐述了目前位移监测模型的进展 ,归纳提出了可用于垂线位移分析的 4种统计模型 ,并结合实例给予说明。这些模型为全面分析垂线位移提供了可能 ,可在不同情况下选择使用。Deformation monitoring and analysis are important contents of dam safety monitoring. Pendulum wire is one of the monitoring methods of dam that have been used widely. From several observed points set inside dam body, information about dam safety condition can be known. In this paper, deformation monitoring statistical model's development has been described based on the former work and authors' recent research. Then, for better analyzing the monitoring information, four kinds of statistical models that can be used in pendulum data analysis are summed up and explained here with practical examples. These models are useful to analyze pendulum deformation overall and can be selected in practical data analysis according to different conditions.
