Abstract: Based on the deformation monitoring data in the last twenty years, the law, value and spatial distribution of the deformation of Jiangxi Jiangkou dam were analyzed in detail. Besides, by regression analysis of monitoring data, the characteristics of horizontal and vertical displacement were understood to evaluate dam behavior.

摘要： 根据江西江口水电站大坝近二十多年的变形监测资料，对大坝变形规律、量值及空间分布情况进行了详细分析。并通过对实测数据的回归分析，掌握了大坝水平和垂直位移的变化发展规律，为评价大坝工作性态提供了科学依据。
