Abstract：
Earth pressure balanced shield machine is used for sandy cobble stratum in Beijing and it is mainly equipped with spoke head or radial plate head. These two head types were compared with each other to introduce the characteristics of radial plate head and discuss the key shield tunneling technique of radial plate head. Based on a sandy cobble stratum shield construction in Beijing Subway Line 9 project, optimizing measures were proposed for radial plate head.
