Taking the installation and debugging of GSM-R system of Shijiazhuang-Taiyuan High-speed Railway as an example,this paper introduces the general situation of GSM-R system,analyzes the causes why the weak field strength exists,and puts forward the method for solving the weak field strength through making rational use of fiber optic repeater,base station and leaky coaxial cable.

Combined with the system of railway composite digital mobile communication of GSM-R,it introduces the selection of the base station,the frequency of multiplexing and the strengthen of weak field,and represents the base station construction on base of carry out the project,to prompt the application of the commutation system in railway commutation construction.
