平潭海峡公铁两用大桥栈桥规模宏大,使用周期长,所处海域风大浪急、水深达46m,海床多有裸露花岗岩地层,海水腐蚀性强,栈桥下部结构设计与施工困难重重。针对不同地质、水深条件,细划栈桥分类,对深水区栈桥下部结构设计参数进行研究与分析,可为此类水域条件下的栈桥下部结构设计提供参考。
平潭海峽公鐵兩用大橋棧橋規模宏大,使用週期長,所處海域風大浪急、水深達46m,海床多有裸露花崗巖地層,海水腐蝕性彊,棧橋下部結構設計與施工睏難重重。針對不同地質、水深條件,細劃棧橋分類,對深水區棧橋下部結構設計參數進行研究與分析,可為此類水域條件下的棧橋下部結構設計提供參攷。

The difficulties in the construction of Pingtan strait hi-rail bridge come from its large scale, long life cycle, diverse ocean environment with deep water, strong wind, exposed granite and heavy sea water corrosion. In view of the different geological conditions and water depth, detailed classification of trestle bridge is employed and researches and analyses are conducted to define design parameters so as to provide references for the design of the substructure of such trestle bridges in similar water areas.
