Abstract The Fuxing Road Tunnel in Shanghai is a double-deck crossing-river project，during execution of which rotational measurement/control system for shield driving has been employed. The high-precision shield horizontal deviation detector independently developed by STEC has satisfied the requirement of pitch accuracy against horizontal deviation of large diameter shield caused by its rotation. Working principles of controlling shields rotation，design criteria of electrical detection and control，electrical principles of shield correction system and its software and hardware make-up are described.
