摘要
堆石混凝土是将专用自密实混凝土充填到堆石体,形成结构紧密的混凝土,具有综合成本低、施工简单快速、低碳环保等优点,适用于水利、水电、公路、铁路与港口等行业的混凝土工程,目前在国内已有大量的工程应用。近年来对堆石混凝土的综合性能进行了一系列的试验研究和数值分析,本文从热学性能、力学性能、长期与耐久性能等方面对堆石混凝土各项性能的研究进行了总结,就其综合性能进行了分析,并提出了进一步研究的问题。
Rock-filled concrete （RFC）, which is formed by filling specific self-compacting concrete into rockfills, is a type of dense concrete, not just environmental friendly but of easy construction, low-heat hydration, and low cost. In China, RFC is widely used in mass concrete projects in hydraulic and hydropower engineering, highway and railway engineering, harbor engineering, etc. Up to the present, comprehensive experimental studies and extensive numerical analysis on its performance have been carried out. This article presents a summary and analysis of its thermal property, mechanical property, long-term performance and durability, and suggests some issues for further studies.
