Abstract：The reasonable cutter head selection and cutter configuration of shield machine are the important foundation to ensure the smooth construction. More complicated and changeable geological conditions may be encountered in the construction of submarine shield tunnel, which puts forward high requirements for the selection of cutter head and its formation adaptability. In order to better guide the engineering practice and research of the submarine tunnel in the Pearl River Delta water resources allocation project, the cutter head and cutter selection and optimization measures of the representative submarine shield tunnel engineering in China was reviewed. Then, major challenges in the construction of submarine shield tunnels and their countermeasures were analyzed. The analysis results show that the key and difficult points of the next research are mainly the research on the theory and technology of cutter adaptability, the research on the wear resisting material of the cutter head and cutter, the development of the wear resisting monitoring device, and the optimization of cutter replacement technology under atmospheric condition.
