| 中文摘要: |
| 全寿命设计理论是基于生命周期造价最低的理念，综合考虑规划、设计、施工以及耐久性设计、管养设计、拆除、回收再利用设计、风险评估及保险策略和全寿命周期成本分析等方面，使桥梁设计达到安全、经济、耐久及环保等。在分析斜拉桥拉索体系特点的基础上，重点比较了平行钢丝拉索和钢绞线拉索的各项技术指标以及两者在施工过程中的特点，结合全寿命设计理论，从全寿命造价最低及可持续发展的角度，得出钢绞线拉索体系较平行钢丝拉索体系优越的结论。建议在斜拉桥的施工中，多应用钢绞线拉索体系。 |
| 英文摘要: |
| Full life design theory is based on the minimum full life cost, which takes into consideration the durability design, management and maintenance design, remove and reuse of structure, risk assessment and insurance strategy, and is aimed to make the bridge design safe, economic, durable and protective to environment. After analyzing the characteristics of cable stay systems, comparing the specification characteristics and the fabrication and erection methods between parallel steel wires cable system and strand cable stay system, based on the minimum full life cost of full life design theory, it is concluded that strand cable system is better than the parallel steel wire cable system. Strand cable system shall be used firstly in cable stayed bridges. |
