Research on Deformation Mechanism of division Pier at the Head of Three Shiplocks of TGP During Construction
三峡永久船闸三闸首中隔墩施工期变形机制的研究

The deformation mechanism of division pier at the head of three shiplocks of TGP during construction is analyzed, based on the safety monitoring results of the deformation of surface and deep position of the division pier. The loose area and effect of bolt support for the division pier are presented. It is proved that as a whole, the division pier at the head of three shiplocks is stable.
