江垭混凝土重力坝，采用全断面RCC筑坝技术．为了保证大坝工程质量，满足合同规范对RCC性能的要求，本工程采取：（1）由大坝安全评审组（CSRP）适时地实施监督、指导和评审工作；（2）实行工程施工监理；（3）建立质量保证体系，把质量目标、措施和责任落实到单位和施工作业环节中；（4）施工质量严加控制．在施工质量控制方面，在正常环境下，根据温控要求、铺筑能力、间歇时间等动态地控制VC值．在特殊情况下，如雨天时，不再摊铺砂浆及灰浆垫层，已入仓的要立即振动、碾压．在热天时，温控的主要措施有风冷骨科、低温用水和全面喷雾，改善小气候．施工工艺例如拌和、运输及摊铺等等都可以满足RCC施工按合同和规范作业．文中还对坝高1／3基础部分混凝土质量成果作出评价．
Jiangya concrete gravity dam, the use of full-face RCC damming technology. In order to ensure the quality of dam works and meet the performance requirements of RCCs, this project adopts: (1) timely implementation of supervision, guidance and assessment by the Dam Safety Review Team (CSRP); (2) implementation of construction supervision; (3) Establishing a quality assurance system, implementing the quality objectives, measures and responsibilities in units and construction operations; (4) Strict quality control of construction. In the construction quality control, under normal circumstances, according to the temperature control requirements, paving capacity, intermittent time and other dynamic control VC value. In exceptional circumstances, such as rainy days, no longer paving mortar and mortar cushion has been warehousing immediate vibration, rolling. On hot days, the main measures of temperature control are air-cooled orthopedics, cryogenic water use and full spraying to improve the microclimate. Construction processes such as mixing, transportation and paving, etc., can be done in accordance with the contract and specifications for RCC construction. The article also made a comment on the concrete quality results of 1/3 basement height dam.
