Research and practice on intelligent construction technology system of Jinsha River hydropower projects

Facing the challenges of complex environment,condition changes,resource flow,structural trans-formation and behavior adjustment of large hydropower projects in the lower reaches of the Jinsha River,an intelligent construction technology system has been established to focus on the whole life cycle safety of large-scale hydropower projects from the engineering planning,construction,and operation.This intelligent system adopts the principle of intelligent closed-loop control of "comprehensive perception,real analysis and real-time control",takes digital and intelligent technologies of resource elements digital management,digital control of business procedures,intelligent control of process flow,accurate analysis of physical costs,structural safety,coupled simulation analysis,and linkage control as its core,the hydropower engi-neering data model like dam panoramic information model DIM as its foundation,and the intelligent con-struction management platform iDam as its main body.Hence,this paper analyzes the key technologies,in-cluding engineering data structure decomposition and coding system,engineering data aware-transmis-sion-sharing technology,the systemic architecture and business architecture of iDam platform,and the per-formance of intelligent construction engineering.Relying on the unified engineering data structure and cod-ing system,the platform iDam is capable to integrate all basis data,environment data,process data,and monitoring data throughout the whole engineering process of the construction.As a result,the analysis func-tion,based on engineering technology and management data,can be applied to different parties including owners,construction,supervision,design,R&D and operation side.This early practice of intelligent con-struction shows that the technical system established by this paper is scientific and feasible,which makes it a good reference for the study and application of intelligent construction technology and management sys-tem in terms of infrastructure.
