Research on double deck beam closure construction based on hanging beam on arch technology

Abstract

This paper established the construction calculation model of the whole bridge through Midas Civil software, and analyzed the mechanical response of the whole and horizontal cables in the construction process in detail. It verified the feasibility and safety of the construction process of “lifting beams on the arch and lifting the bridge deck as a whole in double decks”. The monitoring method, the deviation adjustment technology of the closure opening and the fine-tuning strategy of the top pulling device were proposed to ensure the accuracy of the closure during the bridge deck closure construction of Qingshuitang Bridge.
