Hydraulic integral lifting technology has been widely used in large-span corridor,grid,and truss structures,and the lifting method is becoming more and more flexible.Taking the new building project of Luoyang Science and Technology Museum as an example,this paper introduces the characteristics of the application of large-span floor truss integral lifting technology in the project,as well as the main work contents and precautions in the design and the lifting construction stage,expounds the interface welding technology after the lifting of the project,and analyzes the construction process simulation and structural monitoring of the large-span floor truss integral lifting of the project,in order to ensure the safety of the construction process and the later use of the structure.
