Controlling Technology Research of Deforming due to South-to-North Water Transfer Tunnel down Crossing Subway

Abstract

As one of national important engineering, South-to- North Water Transfer middle line crossed the Beijing subway route 1. Various controlling technologies of deforming were applied during construction of water tunnel in order to control the deformation of the existing subway tunnel. At the same time, automatic monitoring technology was applied too. By the system analysis of monitoring data and controlling measures, the rule of structure deformation is concluded and the validity and fitness of controlling measures are validated. At last, it is useful experience for similar engineering.
