中文摘要:
      阐述了紧水滩拱坝坝顶水平位移的分布及变化规律,根据垂线与交会测点位移坐标特点以及相应拱弧曲线形式,对测点切向位移与横河向位移变化规律不一致的现象进行了分析和解释,指出只有垂线与前方交会测点统一采用大地坐标系统,两者的位移观测成果才能相互印证。
英文摘要:
      The distribution and changing of the horizontal displacement of the dam top of the Jinshuitan arch dam are introduced. According to the coordinate characteristics of the displacement which are obtained by plumbline and forward intersection observation method, and the corresponding arch curve form, the problem that the changing of the tangential displacement of the measuring points is inconsistent with that of the transverse displacement analyzed. It shows that only when the geodetic coordinate system is adopted for both the plumbline and the forward intersection measuring points, can the displacement measuring results of them be consistent.
