Abstract: The rapid development of construction technology has made the BIM technology increasingly influential during the construction stage of projects. In views of the construction characteristics and difficulties of the 220kV power tunnel project of Wanjiali Road in Changsha, the first power shield tunnel in Hunan province, this paper explores the application of BIM technology in the construction stage by referring the innovative BIM applications. The research on BIM technology application is carried out mainly from three aspects of the application of basic function, optimization function and construction management. There have been some applications of BIM technology concluded with significant popularization value, respectively aiming at guiding the field construction, optimizing the construction technology and site layout, and controlling the linear deviation of small radius section of shield tunnel. The application of BIM technology in this project has achieved good results in many areas including quality, safety, progress, construction technology, social benefits, personnel training, and etc., receiving favorable comments by all communities. The research also provides reference and valuable experience for the application of the BIM technology in the field of shield tunnel construction in the future.
