现浇连续箱梁满堂支架施工方案简述

Simple narration construction plan of cast-in-site with houseful support frame on continuous box grider

结合工程实例,阐述了某预应力混凝土连续箱梁满堂支架现浇施工方案、承载力验算要点,并提出了注意事项和改进措施,指出在支架设计时不仅要从支架本身的强度、刚度和稳定性等加以验算,还要对承受上部荷载的地基加以验算,才能确保支架安全。

Comined with the engineering, the paper describes the plan on construction continuous box grider by using cast-in-site with houseful support frame, and checking calculation of carrying capacity with putting forward important matters deserving attention and improve mea- sures. It points out that in the design of supporting frame not only the strength, rigidness and stability of supporting frame should be checked, but also the foundation supporting the upper load should be checked, so that the safety of supporting frame is ensured.
