Design of Broad-Columns Joint and Analysis of Stress for Top-down Construction Method of Underground Engineering

Abstract:

According to the force problems caused by changing of structure forms of broad-column joints when using top-down construction method, this paper introduces the process of top-down construction method and design method of broad-column joint, using finite element software to analyze the stress of ring beam around broad-column joint, which is verified that adopting ring beam is safety and reliable, ring beam can transfer load and bear moment effectively, the strength of outsourcing column will be checked, finally it summarizes the characteristics of ring beam using top-down construction method.
