摘要：

为解决钢筋混凝土漏斗模板支撑体系材料耗费大、工期较长和施工不便等问题，以内蒙古白家海子煤矿一新建钢筋混凝土漏斗为工程依托，提出一种新型吊-拉模板支撑体系。利用Midas Gen有限元软件建立新型吊-拉模板支撑体系的数值模型，并模拟漏斗施工全过程，分析施工过程中该新型模板支撑体系各构件受力及变形情况；另外在实际施工过程中，在结构关键部位布置监测点，跟踪监测漏斗施工全过程的整体位移和各构件应力变化。监测结果表明：新型吊-拉模板支撑体系各构件应力和变形均满足规范要求，新型吊-拉模板支撑体系的可行性得到验证。监测结果与模拟结果的对比表明，相对于数值模拟结果，施工阶段的实测应力和位移误差均不超过10%，说明该数值模型在一定程度可以反映钢筋混凝土漏斗施工模拟的受力和变形规律，为后续相关研究提供理论指导和技术支撑。

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.
