【摘要】：虹杨变电站是与上部建筑结合的深埋地下变电站,能够很好地解决城市用电问题和土地使用紧张问题之间的矛盾,但其在电力系统的应用及研究较少,面临新的挑战,包括上下建筑的协调与转换、转换结构的抗震与防连续倒塌等安全性问题。对比了各种转换结构类型,选择了厚板转换形式,并采用有限元软件对其受力和变形进行了精细分析。在抗震方面,采用振型分解反应谱法,建立了虹杨变电站地上、地下结构的整体三维有限元模型,考虑土的弹性约束程影响,考虑水平和竖向地震力,进行了抗震性能设计,得到了地震作用下上下结构的共同作用及转换厚板的应力变形规律,指导了本工程转换厚板的抗震设计。
[Abstract]:The Hongyang substation is a deep-buried underground substation combined with the upper building, which can solve the contradiction between the urban electricity utilization problem and the land-use tension problem, but the application and the research on the power system are less, the new challenges are faced, including the coordination and conversion of the upper and lower buildings, The anti-seismic and anti-continuous collapse of the conversion structure and other safety problems. In this paper, the types of various conversion structures are compared, the form of thick plate conversion is selected, and the force and deformation of the plate are analyzed with the finite element software. In the seismic aspect, a three-dimensional finite element model of the ground and the underground structure of the Hong Yang substation is established by means of the mode-mode decomposition reaction spectrum method, the influence of the elastic restraint of the soil is considered, the horizontal and vertical seismic forces are considered, and the anti-seismic performance design is carried out, The joint action of the upper and lower structures under the action of the earthquake and the law of the stress deformation of the converted thick plate are obtained, and the anti-seismic design of the conversion thick plate of the project is guided.
