Paper Title:
Application of Pile Underpinning for Strengthening Design of Longgan Bridge
  Abstract

Local scouring around the bridge pier occurs because of flow separation and the development of several vortexes around the pier. Such scour holes can cause a weakness in the bridge which may see cracks occurring on the box girders, especially during flooding. This paper presents a design scheme in which a pile underpinning technique has been adopted for such cases during research into defects in bridges. Furthermore, the finite element model has been established to evaluate the bearing capacity of the bridge before and after adopting this new measure. A large quantity of calculation data indicate that the application of the proposed method performs appropriately and plays an important role in raising the bearing capacity of bridge. The specific program bringing this into effect correctly in a renovation project is illustrated.
