渤海海峡跨海隧道方案研究

Scheme study of Bohai Strait cross-sea tunnel

渤海海峡固定式跨海工程是国家铁路网和高速公路的重要组成部分,跨海通道建成后将取代现有的轮渡运输方式,满足不断增长的交通运输的需求,并会进一步加快环渤海经济圈的发展以及东北老工业基地的振兴。在研究渤海海峡的气象、水文、地质等建设条件的基础上,对桥隧工程方案及隧道线位方案进行了初步比选分析,认为渤海海峡跨海工程宜采用全隧道方案,并且旅顺-蓬莱的隧道连岛线位方案较优,在对该线位浅埋隧道和深埋隧道比较后认为采用深埋方案较优。由于公路隧道存在诸多技术难题,以及工程造价和运营成本都很高,因此,把铁路隧道方案作为首选方案,汽车可通过穿梭列车背负式通过隧道。

Bohai Strait settled cross-sea project is an important part of the national railway network and the highway. Settled cross-sea channel will be built to replace the existing ferry transport,to meet the growing transportation needs. Based on the study of meteorology,hydrology,geology of Bohai Strait,the preliminary comparison of bridge or tunnel scheme and tunnel line position are analyzed. According to the analysis,Bohai Strait cross-sea project should adopt the whole scheme,and Lvshun-Penglai tunnel line bit program is excel-lent,the line position in deep tunnels is optimum. Because there are many technical difficulties of highway tunnel, as well as construction costs and operating costs are high,therefore,the railway tunnel scheme is the preferred one,and cars are carried by trains to cross the Bohai Strait tunnel.
