湛江钢铁基地B型干煤棚施工全过程模拟分析

Construction Process Simulation for Type-B Dry Coal Shed in Iron and Steel Base of Zhanjiang

根据湛江钢铁基地B型干煤棚施工组织设计,采用MIDAS通用有限元软件中的施工分析模块,考虑了结构的几何与边界非线性,对整个施工过程进行模拟分析。获取了整个施工过程中结构的变形与应力,并将其与结构一次加载结果进行了比较。结果表明,采用的"网架累积拼装,胎架逐步滑移"的施工方法安全可靠,施工结束时结构的变形、应力与设计目标虽存在一定差异,但可接受。

According to the construction process of type-B dry coal shed in iron and steel base of Zhanjiang,the constructing simulation block of finite element software MIDAS is adopted to conduct the whole construction process by considering the nonlinearity of geometry and boundary. The deformation and stress distribution of the structure in the construction process are obtained,which are compared with the results of the structure under complete loading. It is shown that the construction method of cumulative assembly and temporary supporting system gradually slip is safe and reliable. Although the final state of the structure in the construction process is different with the design target to same extent,the results are still acceptable.
