摘　　要：泗蚌高速起点段落穿越洪泽湖滞洪区,与新扬高速设置双沟枢纽互通立交。通过比选起点枢纽桥梁、路基方案和桥梁跨径,阐述了双沟枢纽全桥方案的合理跨径。研究了双沟枢纽、T型枢纽和预留改造十字型枢纽,认为此类预留工程采用“一次设计,分期建设”的思路更为节约。The starting section of the Sibang expressway crosses the flood detention area over Hongze lake,and it is connected to the Shuanggou hub interchange of the Xinyang expressway.By comparing and selecting the hub bridge at the starting point,subgrade scheme and bridge span,the reasonable span of the full bridge scheme for the Shuanggou hub is elaborated.The Shuanggou hub,T-shaped hub,and the reserved upgrading cross-shaped hub are studied.It is believed that the idea of"one-time design,phased construction"is more cost-effective for such a reserved project.
