摘要
八车道以上扩建技术标准论证是沪武高速公路扩建的难点和关键点,以该工程为依托,通过扩建技术标准初步论证,并在沪宁高速特别是大交通量硕放枢纽至东桥枢纽段运行情况调研的基础上,针对整体式断面、整体复合式断面和分离式断面方案进行综合比选分析。研究结果表明,从工程规模及安全风险可控角度推荐整体式十车道(客货分行)方案,从审批及安全风险角度推荐平面分离式3+3(客货分行)方案,优先推荐整体式十车道(客货分行)方案。
The demonstration of the reconstruction and extension technical standard of over eight lanes expressway is the difficulty and key point of the reconstruction and extension of Huwu Expressway.Relies on this project,the paper makes preliminary demonstration of the technical standard of reconstruction and extension;meanwhile,based on the research of Huning Expressway,especially the operation of large traffic volume in the hub from Shuofang to Dongqiao,the paper makes comprehensive comparison analysis focus on integral section,integral composite section and separated section plan.The outcome shows that the integral ten lane(passenger and freight separation)scheme is recommended from the perspective of engineering scale and safety risk control;while the flat separated 3+3(passenger and freight separation)scheme is recommended from the perspective of approval and minimum safety risk;overall,priority recommendation of integral ten lane(passenger and freight separation)scheme.
