金塘大桥非通航孔桥桥型方案构思

Conceptual Consideration of Bridge Type for Non-Navigable Spans of Jintang Bridge

根据在建金塘大桥桥址处的气象、水文、地质等自然条件,分析影响长大跨海桥梁非通航孔桥桥型方案的多种因素,并结合国内外已建跨海大桥的经验,从施工可靠性、海上作业量、工期、预制场地、设备、施工组织、技术经济等方面进行综合比较,提出金塘大桥非通航孔桥桥型方案。

In accordance with the natural conditions of climate, hydrology and geology at the site of Jintang Bridge that is now being constructed, this paper analyzes various factors that may affect the bridge type alternative selection for the non navigable spans of the long span sea-crossing bridge and also in the light of the experiences from the sea-crossing bridges having been completed at home and abroad, the paper proposes the bridge type for the non-navigable spans of Jintang Bridge through the comprehensive comparisons of the construction reliability, work load over sea, construction time schedule as well as precast yard, equipment, construction organization, techniques and economy.
