随着我国电网建设的高速发展,1000kV特高压变电站不断建设,在特高压变电站设计过程中,通过对1000kV自立式格构构架梁柱断面选择和多角度风荷载、温度作用效应及地震作用效应等方面的分析,掌握柱用钢量的变化趋势,以及温度作用效应和地震作用效应对构架的影响,以期达到节省用钢量、降低工程造价的目的,使结构具有更好的经济效益。 With the rapid development of China’s power grid construction, the construction of 1000kV UHV substations is under continuous construction. During the design of UHV substations, the cross-section selection of 1000kV free-standing structures and the multi-angle wind load, temperature effect and earthquake effect In order to achieve the purpose of saving the amount of steel and reducing the construction cost, the structure has better economic benefits.
