摘　　要：为保障轨道交通高架区间工程的安全性与稳定性,文章研究基于钢管贝雷架支撑体系的轨道交通高架区间工程施工技术。针对所选工程区域设计钢管贝雷架支撑体系结构,并选取321型贝雷梁、I14工字钢、竹胶板等材料作为支撑体系施工材料。通过地基处理、架设钢管支撑、工字钢横梁搭设、贝雷梁搭设及模板搭设等步骤,实现钢管贝雷架支撑体系施工。采用模拟验算方式计算支撑体系的地基承载力、抗弯能力、抗剪能力及在风力作用下的抗倾覆稳定性。模拟分析表明:该支撑体系在风力作用的最大位移值仅为1.73mm,具有较强抗倾覆性;支撑体系的梁底模板与腹板范围内的小方木结构的抗弯、抗剪能力较强;地基具有较大的承载力,同时贝雷梁所受盘扣支撑、底部方木、模板及贝雷梁自重产生的永久荷载较低,可保障支撑结构稳定。In order to ensure the safety and stability of the elevated section engineering of rail transit,the construction technology of the elevated section engineering of rail transit based on the steel tube Bailey support system is studied.Design a steel pipe Bailey support system structure for the selected project area,and select 321 type Bailey beams,I14 I-beams,bamboo plywood and other materials as the construction materials for the support system.Through the steps of foundation treatment,installation of steel pipe supports,installation of I-beam crossbeams,installation of Bailey beams,and formwork installation,the construction of steel pipe Bailey support system is achieved.Using simulation verifi cation method to calculate the foundation bearing capacity,bending capacity,shear capacity,and anti overturning stability of the support system under wind force.
