摘要
结合某工程实例,阐述了某预应力混凝土连续箱梁桥直线段满堂支架现浇施工方案、承载力验算方法,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。
On the background of an engineering example,this article describes the construction plan and bearing capacity methods of a continuous prestressed concrete box girder bridge with full support.Then it points out that not only the strength,stiffness and stability to be checked,but also on the upper load bearing foundation to be checked to ensure safety of the support.
