Abstract

To improve the penetration accuracy of 8 kmlong Wangjing tunnel on BeijingShenyang passengerdedicated line, various intunnel plane control survey methods are comparatively analyzed, and combination surveying methods of traverse survey + gyrostatic orientation survey and traverse survey + gyrostatic orientation survey + vertical projection hole survey are applied in the right and left lines of a shield tunnel, respectively, resulting in a small penetration error. It can be concluded that for the long and large deadend shield tunneling with a length of more than 3 km, the method of traverse survey + gyrostatic orientation survey for guiding and vertical projection hole survey 300~500 m before shield receiving can significantly improve the penetration accuracy.

Key words： ; shield tunnel; control survey; traverse survey; gyrostatic orientation survey; vertical projection hole positioning; penetration accuracy; deadend tunneling
