摘　　要：通过彭水水电站大坝工程碾压混凝土现场工艺生产性试验,对拌和工艺、碾压工艺、层面处理技术措施、变态混凝土施工工艺等进行了试验研究,经机口取样、钻孔取芯、压水试验和原位抗剪试验,验证了室内试验选定的碾压混凝土配合比的可碾性和合理性,确定了合适的施工工艺,为工程施工提供了依据。As far as the RCC dam construction of Pengshui Hydropower Station concerned some problems, an experimental research on mixing technology, roller compaction technology, layer surface treatment and construction technology of GEV-RCC was performed. Through specimens taken from a mixing plant, core boring and water pressure tests and field shear tests, the rollability and rationality of the mix proportion of concrete selected through laboratory tests were validated and suitable construction technology was determined. The test results provided a basis for project construction.
