The construction technique of the launching shaft of shield in Yaohuazhi Road tunnel in Shanghai is presented in this paper. The construction of the deep shaft in the soft stratum with the pressure groundwater is introduced, which faces the strict environment protection requirement. The fast construction after adopting the appropriate method is performed to minimize the influence on the environment.
Key words： tunnel ; shaft ; diaphragmwall ; wellpoint dewatering ; environment protection
