基于有限元法的GIL典型模块静动力仿真研究

Research on Static and Dynamic Simulation of Typical GIL Module Based on Finite Element Method

GIL一般用于复杂工况,在实际工程应用中,GIL工程路径极其复杂,敷设过程涉及隧道、沉井等方式,需要避让不同类型的城市地下管线。以国内某工程GIL为案例,对该GIL工程的典型模块开展结构建模,进行多荷载组合下的静动力分析,验证处于复杂受力状态下的GIL结构是否能正常运行,并根据仿真结果对典型模块的支架布设进行优化处理,以期为后续GIL工程的设计、运行提供有益借鉴。

GIL is generally used for complex working conditions.In practical engineering applications,GIL engineering path is extremely complex,and the laying process involves tunnels,caissons and other ways,which need to avoid different types of urban underground pipelines.Taking a domestic GIL project as an example,this paper carries out structural modeling of the typical module of the GIL project,carries out static and dynamic analysis under multiple load combinations,verifies whether the GIL structure can operate normally when it is in a complex stress state,and optimizes the layout of the support of the typical module according to the simulation results,so as to provide a useful reference for the design and operation of subsequent GIL projects.
