摘要
为了进一步推动渤海海峡跨海通道的规划与兴建,对其跨越方案进行了初步研究。通过分析渤海海峡地形、地貌、地质、气候、海洋、环境等基本建设条件,提出了采用"南桥北隧"的组合方案,即海峡北部采用海底隧道,南部利用中途各岛屿建设跨海大桥。运用Google Earth地理信息软件,获取沿线岛屿及海底的地形数据,绘制沿线地层纵剖面图,结合沿线岛屿和水深特点,对隧道埋深和桥梁线路进行布设和方案构想,给出各种方案的总长度。最后提出下一步需要研究解决的问题及相关建议。
The option for Bohai Strait Sea-crossing Fixed Link is studied in order to promote the planning and construction of the fixed link. The basic construction conditions, such as the topography, landform, geology, climate, ocean and environment, are analyzed and the option of ＂bridge in the south and tunnel in the north＂ is proposed. The topographic data of the islands and the sea bottoms are obtained through the software of Google Earth and the longitudinal profile of the terrain of the fixed link is prepared. The cover of the tunnel and the alignment of the bridge are proposed on basis of the characteristics of the islands and the depth of the seawater. Finally, some issues to be further studied are provided and some suggestions are made.
