Abstract: To solve the problems of high material consumption, long construction period, and inconvenient construction of reinforced concrete funnel formwork support system. This article proposes a new type of suspension tension formwork support system based on a newly built reinforced concrete funnel in Baijiahaizi Coal Mine, Inner Mongolia Autonomous Region. Using Midas Gen finite element software to establish a numerical model of a new type of suspension tension formwork support system, and simulate the entire process of funnel construction to analyze the stress and deformation of each component of the new formwork support system during the construction process; In addition, monitoring points are arranged at key parts of the structure during the actual construction process to track and monitor the overall displacement and stress changes of each component throughout the funnel construction process. The monitoring results show that the stress and deflection of each component of the new suspension tension formwork support system meet the specification requirements, indicating the feasibility of the new suspension tension formwork support system. Meanwhile, by comparing and analyzing the monitoring results with the simulation results, it can be concluded that the measured stress and displacement errors during the construction phase do not exceed 10% compared to the numerical simulation results. This indicates that the numerical model can accurately reflect the stress and deformation of reinforced concrete funnel construction simulation to a certain extent, providing theoretical guidance and technical support for subsequent related research.
