素万纳普机场多种工具式支撑模板体系安全性分析

Safety Analysis of Multiple Tool-typed Supporting Formwork System for Suvarnabhumi Airport

泰国素万那普机场新航站楼主体结构长度约为1 070m,宽度中段最宽处约为80m,两端最窄处为47m,楼层板为后张法预应力无梁板。针对泰国模架供应商规模小和工程实际特点,选取了多种工具式支撑模板体系,通过理论计算和有限元分析,支撑体系承载力和稳定性满足要求,能确保施工过程安全。

The main structure of the new terminal building of Suvarnabhumi Airport in Thailand is about1 070 m in length,the middle section is about 80 m in width,the narrowest part at both ends is 40 m in width,and the floor slab is post-tensioned prestressed flat slab.In view of the small scale of most formwork suppliers in Thailand and the actual characteristics of the project,multiple tool-typed support formwork systems are selected.Through theoretical calculation and finite element analysis,the bearing capacity and stability of the supporting system meet the requirements,which can ensure the safety of the construction process.
