Research on the Concrete Structure Deformation Properties of Xiangjiaba Ship Lift Tower

Abstract

The passing dam building of Xiangjiaba water conservancy project adopts gear-rack climbing vertical structure. The structure demands highly on the deformation compatibility of relative displacement between tower and nut column, and rack and guide. If it is constructed poorly, it will directly influence the ship lifts running and construction period. The paper takes this as its key research object. 3D FEM is used to analyze the tower structure, mainly calculating the deformation of the tower under the temperature, weight, wind load and other loads in a normal single case and combination cases. By focusing on the theory analysis of the important parts such as nut column, rack and guide, the structures deformation fitness, this paper offers a fair theoretical reference and technological guidance to the construction of every part of the tower.
