一、观测墩观测墩是进行坝体位移观测的主要工作基点。它的结构形式、质量的好坏、使用是否方便等,是关系到位移观测工作能否顺利进行的重要保证。我们在里石门混凝土双曲拱坝的位移观测工作中,通过多次试验,在过去贯用结构的基础上,对它进行了一些改进,设计了一种体积较小、制作简单、整体稳固、观测员站立方便的混凝土观测墩(见图一、图二)。
First, the observation pier Pier observation is the main work of the dam displacement observation point. Its structural form, quality is good or bad, the use is convenient, is an important guarantee related to whether the displacement observation can be carried out smoothly. In the displacement observation work of Lishimen Concrete Double Curvature Arch Dam, through several experiments, based on the past structure, some improvements have been made to it, and a new design method of small displacement, simple fabrication, Observers stand convenient concrete observation pier (see Figure I, Figure II).
