These towers areapproximately 100 m high for large rivercrossing projects on 220 kV and 500 kVdesigned by the East China Electric PowerDesign lnstitute (ECEPDI) since 1958.The paper also introduces thecharacteristics, technical and economicparameters of the four typical towersdesigned by ECEPDI such as the concretechimney-type tower, steel tubular tower,guyed tower and compound angle steel tower.展开更多
为研究拉线初张力对±800 k V特高压双柱悬索拉线塔抗风性能产生的影响,分别取拉线初张力为其设计承载力的15%、20%、25%,进行了塔线体系气动弹性模型的风洞试验。试验结果表明:拉线初张力的改变对荷载状态下塔线体系的受力性能影...为研究拉线初张力对±800 k V特高压双柱悬索拉线塔抗风性能产生的影响,分别取拉线初张力为其设计承载力的15%、20%、25%,进行了塔线体系气动弹性模型的风洞试验。试验结果表明:拉线初张力的改变对荷载状态下塔线体系的受力性能影响显著,且对双柱支座反力和拉线拉力的影响呈非线性关系,应对拉线初张力进行优化选取。展开更多
