摘　　要：基于陕西省燃气产业研发与孵化基地项目,设计一种用于大跨度高空连廊钢筋混凝土浇筑施工的贝雷梁平台。考虑提高整个支撑平台体系安全性和稳定性,采用预埋件与箱形钢牛腿板结合,并基于ANSYS有限元软件对钢牛腿进行三维实体模拟。整体空间连廊结构采用SAP2000有限元软件对钢支撑平台体系进行数值模拟分析并优化。经实践检验,该支撑平台体系施工快速、安全、高效,可有效解决高空大跨度钢筋混凝土连廊施工中的技术难题。Based on the Shaanxi Provincial Gas Industry R&D and Incubation Base project,a Bailey beam platform for the reinforced concrete pouring construction of long-span high-altitude corridors is designed.In order to improve the safety and stability of the entire support platform system,this paper adopts embedded parts and steel box-shaped corbel plates,and uses ANSYS finite element software to carry out three-dimensional solid simulation of the steel corbels.The overall space corridor structure uses the SAP2000 finite element software to carry out numerical model analysis and optimization of the steel support platform system.After practical test,the support platform system is fast,safe and efficient in construction,and can effectively solve the technical problems in the construction of large-span highaltitude reinforced concrete corridors.
