普定水电站碾压混凝土拱坝及防渗研究

本文论述了普定水电站碾压混凝土拱坝的设计、施工、材料和坝体温度场的特点和研究成果。介绍了施工中期对碾压混凝土的质量检验成果所进行的分析研究和评价，论证了该坝二级配富胶凝材料碾压混凝土的密实性和抗渗性能已达到或接近常态混凝土的指标，为取消碾压混凝土坝上游面丙乳砂浆防渗层的可行性和工程决策提出了充足的论据。通过水库蓄水后碾压混凝土坝防渗效果的检验，证明成果好，碾压混凝土坝完全可以依靠碾压混凝土自身达到防渗要求。

The Research on Roller Compacted Concrete Strength and Leakproof of the Puding Station Arch Dam

The paper describes the research and evaluation of the design, construction, and test issue of the roller compacted concrete arched dam of the Puding Hydropower Station. The research results led to the decision that impervious layer at the upstream face of the dam may be cancelled, dam's leak proof is enough by roller compacted concrete. A11 these are verified by the reservoir's impounding and the test of bore samples from dam body.
