摘　　要：通过建立石浦高架桥某跨现浇箱梁满堂支架的有限元模型,计算分析支架系统的轴力、拉压应力及位移,以验证支架系统的安全性及数值计算的可靠性,结果表明:支架最大应力值与位移值均未超过钢管的强度值,支架系统的刚度和稳定性满足施工要求。Through establishing finite element mode of crossing-Shipu bridge scaffold, the paper analyzes axial force, pulling stress and displace- ment of support system, and testifies the support system safety and numerical calculation reliability. Results show that ： the maximum stress value and displacement value of the support system don＇ t exceed steel pipe strength value. In additional, the support system rigidity and stability meet construction demands as well.
