最近20年来,乌克兰水工设计院对第聂泊河上的梯级电站进行了揭示水工建筑物变形特性的综合研究与观测。建筑物垂直位移的确定:建筑物的垂直位移,用几何水准测量的方法确定;其实质在于:在规定的观测周期内,按照设置在建筑物上的检测标志,敷设水准路线。每一检测标志的沉陷,当然也就是所在建筑物的沉陷,由相邻两观测周期内该标志绝对高程之差以及整个观测周期对第一观测周期高程之差来确定。
In the recent 20 years, the Ukrainian Hydraulic Design Institute has carried out a comprehensive study and observation of cascade hydropower stations on the Niepo River to reveal the deformation characteristics of hydraulic structures. The vertical displacement of buildings: The vertical displacement of buildings is determined by the method of geometric leveling. The essence lies in: Laying the standard route according to the test marks set on the buildings within the specified observation period. The subsidence of each test mark, of course, is the subsidence of the building where it is located, determined by the difference between the absolute elevation of the mark in the two adjacent observation cycles and the difference between the elevation of the entire observation cycle and the first observation cycle.
