Outline
In order to response the request of hydraulic digital twin, this paper studied how it implement in long linear engine hydraulic project so that the manage system can show any position and any changes of the project. The data linkage inquiry method in both two and three dimension and the shortest distance algorithm innovatively were proposed based on BIM, GIS and geological profile graph. It is implemented through data fusion, data structure design, software design etc., which can make digital scene and geological profile graph's view move and inquire together. The user can immediately acquire mileage, geological conditions, design section, construction and operating state through moving and pre-clicking the cursor. It's proved in a certain water diversion project that the project manager can inquire and acquire real-time project information immediately by using this method without inspect the whole engineering. This method lays the foundation of real-time data inquiry, engineering safety intelligent analysis and production operation management, which implement engineering digital twin to some extent.
