突变理论在马鞍山长江公路大桥桥型论证中应用
|
摘要
采用以突变现象为研究对象的系统理论,从经济、美观、航道适用性、施工和维护难易度等方面出发,对马鞍山长江公路大桥左汊主桥4个桥型方案(主跨2×1 080 m三塔两跨悬索桥方案、主跨1 388 m两塔悬索桥方案、主跨1 180 m两塔斜拉桥方案、主跨2×850 m三塔斜拉桥方案)进行了比较和论证,指出采用2×1 080 m三塔两跨悬索桥方案是合理可行的。
Based on mutation phenomenon as the research object of the theory of the system,to the four bridge type schemes( a three-tower suspension bridge with main spans 2 × 1 080 m,a two-tower suspension bridge with a main span 1 388 m,a two-pylon cable-stayed bridge with a main span 1 180 m,a three-pylon cable-stayed bridge with main spans 2 × 850 m) of the Ma'anshan Changjiang highway bridge main span,from the economy,beauty,channel applicability,construction and maintenance difficulty of comparison and demonstration,it pointed out that using the 2 × 1 080 m three-tower and two span suspension bridge was reasonable and feasible.
