摘要
从面板混凝土原材料选择、配比优化及施工质量保证三方面提高混凝土自身抗裂能力,通过现场碾压试验确定堆石坝体冬季低温填筑参数,保证混凝土面板下方堆石体平稳坚固,以防止面板裂缝产生,并给出解决面板裂缝质量缺陷的技术措施,希望为以后类似工程提供借鉴。
From the panel selection of concrete raw materials,optimization and construction quality assurance three aspects to improve concrete anti cracking ability,through the field compaction test to determine the temperature parameters of rockfill dam filling in winter,to ensure that the concrete panel rockfill smooth solid panel to prevent cracks.The technical measures to solve the quality defects of panel cracks were given in the hope of providing reference for similar projects in the future.
