摘要
在公路桥盖梁支架临时结构设计和施工中,通常在施工前对支架进行设计和方案选取,决定结构和施工的安全性,文章利用MIDAS/CIVIL有限元软件建模并配合手算,经过施做过程检验,从而得出选用材料、最优搭设方案和构造措施,从而做到工艺简单、安全可靠、成本较低、方便适用,可在类似的工程中推广和应用。
In the temporary structure design and construction of highway bridge cover beam bracket,usually before the construction,the bracket is designed,and the scheme is selected to determine the safety of the structure and construction. In this paper,the finite element software of MIDAS/CIVIL is used to model. Cooperated with manual calculation and through actual process testing,the selection of materials,the optimal erection scheme and the construction measures are obtained. The technology is simple,safe,reliable,low cost,convenient and applicable,and it can be applied in similar projects.
