摘　　要：为提高混凝土塔筒门洞的受力性能,对现有塔筒门洞形式进行优化,通过对方形门洞、圆弧形门洞、加厚形门洞和外包钢壳圆弧形门洞等4种布置形式的门洞进行有限元分析计算,对比分析其抗压和抗疲劳性能。结果表明,外包钢板圆弧形门洞的抗压和抗疲劳性能最佳。此外,文章还提出了相应的结构优化方案。研究成果可为混凝土塔筒门洞结构设计提供一定参考。In order to improve the mechanical performance of concrete tower doorway,the existing type of tower doorway is optimized,and the four types of square door,circular arch door,thickened door and circular arch door with steel shell are analysed by finite element analysis,and their compression and fatigue resistance are compared.The results show that the compression and fatigue resistance of the circular arch door with steel shell is the best,and the corresponding structural optimization scheme is proposed.The research results can provide some reference for the structural design of concrete tower doorway.
