紧水滩水电站拦河坝系国内第一座混凝土三心双曲变厚拱坝。为了在施工、运行期间对拱坝进行安全监测,也为今后薄拱坝的建设积累有益的原型观测数据和资料,我们进行了以变形和渗透为主要内容的大坝原型观测,并采用多种观测手段进行了对照验证。本文拟扼要介绍原型观测的设计和观测成果的初步分析,供有关人员参考。 Jishuitan Hydropower Station dam system is the first concrete three heart hyperbolic thickening arch dam. In order to monitor the safety of the arch dam during construction and operation and to accumulate useful prototype observation data and data for the construction of the thin arch dam in the future, we carried out the prototype observation of the dam with deformation and infiltration as the main contents, Observed by means of comparative verification. This article will outline the preliminary analysis of the prototype observation design and observation results for reference by the relevant personnel.
