With development of underground space, the shield tunneling method have been widely adopted due to its unique advantages. However, there is still many technical and theoretical problems need to be improved in the construction. Based on the project of metro line 1 in Hangzhou city, typical problems of shield tunnel construction in sandy soil are analyzed. The problems of ventilation system, cooling water circulation system, foaming system and conveyor belt system are represented in detail. Controlling of proper propelling force is optimized by parameter sensibility analysis. Aiming at these problems, improvement measures are proposed and successfully used in the project. The improvements can be taken for reference in similar projects.
