Abstract: The smoothness of emplacement of heavy gas turbine depends heavily on the installation quality of the gas turbine base plate,and the installation quality of the base plate will also directly affect the load distribution of gas turbine.In this paper,the installation of the base plate of General Electric（GE） 9 F.05 gas turbine is taken as an example,the problems that often occur when the base plate is installed are analyzed,and the concrete treatment methods are put forward,which can provide important experience and reference for the infrastructure installation of other similar projects.
