For the purposes of satisfying different architectural styles, reasonable and economic strcutural system, five cable arrangement schemes were given and comparative analyses on mechanical performances of the stucture were conducted. The results show that the mechanical properties of the 3rd to 5th cable arrangement schemes are better. The study results provide basis to reveal mechanical property and change law for internal force and displacement of single-layer reticulated spherical shell with circumferential folded line with different cable arrangements, and also provide reference for the preliminary design, optimal design and comparison of different schemes for this kind of spherical shell structure.Keywords:circumferential folded line; single-layer reticulated spherical shell; suspendome; cable arrangement scheme*国家自然科学基金重点项目（56038050），杭州市十大产业企业技术创新团队项目，浙江大学建筑设计研究院有限公司院士工作站项目。作者简介：郑晓清，博士，一级注册结构工程师，Email: zheng_xiaoqing@126.com。参考文献［1］郭佳民.弦支穹顶结构的理论分析与试验研究［D］.杭州:浙江大学,2008.［2］张爱林,刘学春,王冬梅,等.2008奥运会羽毛球馆新型弦支穹顶结构模试验研究［J］.建筑结构学报,2007, 28(6):58-67.［3］董石麟，郑晓清. 环向折线形单层球面网壳及其结构静力简化计算方法［J］.建筑结构学报,2012,33(5): 60-65.［4］董石麟，郑晓清. 节点刚、铰接时环向折线形单层球面网壳静力和稳定性能的分析研究［J］. 建筑钢结构进展, 2013,15(6): 1-11.［5］郑晓清，董石麟，白光波，等. 环向折线形单层球面网壳结构的试验研究［J］. 空间结构，2012,18(4)：3-12.［6］董石麟，郑晓清. 葵花形开孔单层球面网壳的机动分析、简化杆系模型和计算方法［J］. 空间结构，2010,16(4)：14-21,54.
