Paper Title:
Study on Tower’s Stability and Construction Control of Basket Handle Arch Bridge when Vertically Rotating
  Abstract

Taking a half-through concrete-filled steel tube(CFST) tied arch bridge with span arrangement (40m+200m+40)m as an example, this paper make a study of tower’s stability, construction monitoring and control during vertical rotation of the arch rib. Using the finite element method to simulate the rotation construction phase of the bridge by the way of normal erection calculation, the effect of several different factors to the tower’s instability is analyzed in detail. On the basis, we obtained the effective measure to ensure the tower stable. Meanwhile, survey the tower’s stress and deformation to supervise the tower during the rotation construction. Finally control tower top displacement and its foot stress to guarantee the rotation construction of the CFST arch bridge quality and safety.
