RCC CONSTRUCTION TECHNOLOGY OF DOUBLE-CURVATURE ARCH DAM OF LONGTAN RESERVOIR

摘要：

　　Longtan reservoir is the first high RCC double-curvature thin arch dam with the maximum height of 85m in Sichuan province,which characterized with its complex geological conditions,strong technology and great construction difficulty.This paper mainly introduces the material selection and mix ratio design of RCC,the construction process of mixing,transportation,compaction and maintenance,and the construction technology of adding MgO to dam and the temperature control measures adopted in construction,which ensure the quality of RCC construction and greatly improve the production effectiveness.
