普定碾压混凝土拱坝原型观测与分析反馈

Prototype Observation and Analysis feedback of Puding RCC Arch Dam

随着坝工技术的发展，碾压混凝土筑坝越来越受到坝工界的广泛重视，然而作为研究和发展这一新技术重要手段的原型观测，却未能跟上其发展的需要。为此，国家在“七五”及“八五”期间均设立了专门的研究子题。结合普定水电站工程，开展的“八五”科技攻关中的一个子题，对碾压混凝土拱坝内部原型观测设计、观测仪器埋设技术进行了研究。通过对观测资料的分析，验证了坝体选料及配合比的科学性、施工工艺的先进性，并对坝体施工质量及坝体的安全稳定进行了评估。

With Puding Hydroelectric Project,the paper studies prototype observation design and embedding technique for observation instruments of RRC arch dam. After observation data are analyzde, it is provde that materials election and mixed rate are scientific and construction process is advanced, In addition,construction quality, and safety and stability of the dam body are assessed in this paper.
