摘要
Abstract
The crest elevation of the concrete double curvature arch dam for Jinping I Hydropower Station is 1 885 m, while the foundation surface elevation is 1 580 m with the maximum dam height of 305 m; for which a total of 25 transverse joints are arranged and then the dam body is divided into 26 sections. Through the joint grouting, not only the loading condition of the dam can be improved, but the safety margin for the shallow anti-sliding stability of the dam foundation can also be enhanced; which can makes the dam body have a certain monolithic effect to increase the reliability of the operation safety of the dam. The construction technology of the joint grouting for the dam is introduced herein along with the description made on the main problems possibly occurred during the construction and their treatment measures.关键词
