Abstract

Abstract: Ground reinforcement near shield launching and arriving shaft is used to guarantee the safety of the shield tunneling. Some issues and their treatments of launching and arriving for earth pressure balance shield tunneling in waterrich and silty strata of No.7 bid section on line 1 of Wuxi Metro are presented. The paper can provide reference for earth pressure balance shield tunneling in waterrich and silty strata.

Key words: shield launching, arriving, waterrich and silty strata, reinforcement
