Abstract: To ensure the construction quality for the flood-damaged embankment reconstruction, the intelligent rolling and real-time quality monitoring of the dam, the intelligent monitoring on the construction quality of the high-pressure jet grouting pile of cut-off walls, and the intelligent monitoring on the construction quality of the TRD of the cut-off walls were developed. The real-time online monitoring and fast feedback control of the quality parameters of the whole process of dam filling rolling, high pressure jet grouting and TRD construction were realized. At the same time, with the intelligent monitoring system as the link, an integrated management and control system with multi-party deep participation was constructed. The application of engineering examples showed that intelligent management and control technology provided advanced technical means for project construction quality management, solved the problem of quality control when management personnel is unable to provide full coverage, provided strong technical support for building high-quality projects, and also promoted the development of dam construction management to digitization and intelligence.
