【摘要】 吊拉组合桥是一种在大跨径桥梁中极具竞争力的新型桥梁结构,已越来越多的受到了国内外桥梁专家和学者的关注,但同时吊拉组合桥梁结构设计和施工当中所存在的一些问题还在困扰着人们,这使得一些桥梁设计专家在选择桥梁结构形式时对吊拉组合桥总是敬而远之。本论文就是针对吊拉组合桥在设计以及施工当中所存在的技术难题和施工难题进行研究,提出了解决这些问题的关键技术和施工工艺,并且进行了详细的计算分析和讨论。在本论文的最后还对这些关键技术和施工工艺进行了技术经济方面的简要分析。通过本文的研究和讨论,解决了长期以来人们对吊拉组合桥所存在的种种困扰,大大增强了吊拉组合桥修建的可行性以及吊拉组合桥梁在大跨径桥梁修建当中的竞争力。更多还原

【Abstract】 Combined cable-stayed suspension bridge (CCSB) is a kind of new style bridge with intense competitive power in large span bridge . It has already caused comprehensive domestic and foreign experts’ attention . But many problems perplex people when designing and constructing CCSB . So , some bridge experts often breed out CCSB while they choose bridge style .This paper brings forward construction crafts and key technics that can solving these problems among designing and constructing CCSB , and also makes detailed calculations analysis . At last, it makes technical economy analyses to these construction crafts and key technics .Many perplexes to CCSB’S designing and construction have been solved through calculations and analyses in this paper . At the same time, the teasibility of constructing CCSB and its competitive power have already been enhanced by far .更多还原
