大坝的不均匀沉陷和倾斜变形,关系到大坝的稳定和安全。但由于种种原因,已建大坝一般都没有直接测量这种变形的设施,这就需要用其它变形资料来推断。就变形特性而言,大坝的不均匀沉陷和倾斜,主要是坝基在垂直方向的位移所引起的。因而可以用大坝的垂直位移来判别大坝的不均匀沉陷和倾斜。 Uneven subsidence and slope deformation of the dam are related to the stability and safety of the dam. However, due to various reasons, the dam has generally not directly measure the deformation of the facilities, which need to use other deformation data to infer. In terms of deformation characteristics, the uneven subsidence and inclination of the dam are mainly caused by the displacement of the dam foundation in the vertical direction. Therefore, the vertical displacement of the dam can be used to judge the uneven settlement and inclination of the dam.
