介绍了某水库三维变形监测网的布设和观测方法,对长期观测获取的变形监测数据资料进行了绘图,并对大坝变形特征进行了分析。监测结果显示,大坝整体仍处于下沉态势,2009年以后水平竖向位移速度都变得缓慢,整个坝体中变形量最大的区域出现在中坝中段和中坝西段,其次为中坝东段和西坝,东坝变形量为最小。库水位的变化是导致大坝变形的主要原因,而库水深度是引起大坝变形不均匀的主要原因。
The layout and observation methods of three-dimensional deformation monitoring network of a reservoir are introduced. The deformation monitoring data obtained from long-term observation are plotted, and the deformation characteristics of the dam are analyzed. The monitoring results show that the whole dam is still in a subsidence state. After 2009, the horizontal vertical displacement speed becomes slow. The area with the largest deformation in the whole dam appears in the middle section of the middle dam and the middle section of the middle dam, followed by the middle dam East section and West dam, East dam deformation is the smallest. The change of reservoir water level is the main reason that causes the dam deformation, and the reservoir water depth is the main reason causing the uneven deformation of the dam.
