Suspend - dome is a new multiplex structure system composed of single - layer spherical latticed shell above, prestressed cables below and braces bars used to link them. compared with single - layer latticed shell and cable dome, suspend - dome can cross a larger span economically and reasonably
弦支穹頂（ suspen - dome ）是由上部的單層球面網殼，下部的預應力環索和斜索以及聯系二者的撐桿組成的一種新型的復合結構體系。The influence of some design parameters, such as density of net, rise - span ratio, height of strut, prestressing tension of cable, are analyzed, some economical and reasonable optimized parameters were gotten
分析了網格密度、矢跨比、撐桿長度、鋼索預應力值等設計參數對弦支穹頂各項性能指標的影響，得到了經濟合理的設計參數取值范圍。However, ajoint support of alluvial rock bolt with a double - layer of wire mesh can also besatisfactory in the same type of unfavorable ground conditions, with better economicbenefit
而在某工程的地下洞室不良地質地段的支護中採用了雙層鋼筋網同管式錨桿聯合支護獲得成功，產生了與鋼支撐同樣的支護效果，並帶來了良好的經濟效益。Compared with the rope fixer of old tye crane, ss100 use wall - ties to fix the guide column. so it is much safer and covers fewer site area. further more, the protector against rope break, landing protector and monitor make ss100 much safer and reliable
採用附墻撐桿固定導軌架，比井架式升降機採用的銅絲繩纜網固定更安全且佔地面積小，其中設置的防斷繩和停層保護器安全可靠，可視式監視器更是一種創新。Because slts owns too many parts and complex supporting conditions, and invalidation of few parts or nodes does not have significant effect for structural bearing capacity, research orientation is transferred to structural support system in chapter 4 of the thesis. limited loading capacity and safety index of steel bracket of slts are calculated and analyzed for providing theoretic upper limit to safe operation of support system
由於網架結構的桿件眾多，結構支撐條件復雜，少數桿件或節點的破壞對于結構的正常承載無顯著影響，本文在第四章將研究方向轉向網架結構的支撐體系，計算分析網架結構支撐鋼牛腿的極限承載能力和安全儲備，為支撐系統的正常工作提供一個理論上限。分享友人
