渤海海峡跨海通道是连接我国山东半岛与东北地区的战略性工程，对于加快环渤海圈的经济发展及振兴东北老工业基地都有重大意义。通过全面分析渤海海峡通道建设的战略价值，对渤海海峡通道的工程方案及投融资方式进行了详细规划，认为渤海海峡跨海工程宜采用旅顺—蓬莱的全隧道方案，并将铁路隧道方案作为首选，汽车通过穿梭列车背负过隧道；隧道施工采用tunnel boring machine（TBM）法+钻爆法，在我国现有隧道修建的技术水平与经济能力下是可行的，施工风险水平在可接受范围；参考国内外跨海工程建设情况以及渤海海峡跨海通道工程项目特点，本项目融资适宜采取build-operate-transfer（BOT）模式。

Bohai Strait cross- sea channel is a strategic project which connects Shandong Peninsula and Northeast regions, and it is very important for speeding up the economic development of the Bohai-ring and revitalizing the northeast old industrial base. Through a comprehensive analysis of the strategic value of Bohai Strait channel,the engineering solutions and investment and financing methods are planned. According to the analysis, the Bohai Strait project should adopt Lvshun—Penglai tunnel option, and the railway tunnel is the preferred solution, cars are carried by trains to cross the Bohai Strait tunnel;tunnel boring machine (TBM)+ drilling and blasting method is used in the construction of the tunnel,this method is feasible in our existing tunnel built and economic capacity, and the construction risk is acceptable. In accordance with cross-sea project of domestic and international and the characteristics of Bohai Strait cross-sea channel, the build-operate-transfer (BOT) financing model is suitable.
