摘要/Abstract

摘要： : 为早日建成跨越渤海海峡的快速通道,首先,介绍科学的比选方案,并提出海底真空管道高铁概念,分析其优缺点;然后,根据渤海海峡海况与地形地质特征,建立通道范围内烟台—大连间A、B、C、D 4 条可能路径的平面线路走向和纵断面模型;最后,通过线路方案比选研究,得出以下结论: 1)海底高架、沉管铺设或海底浅埋是较为经济、理想的方式,优于海底隧道; 2)A 线全长约110 km,经由海域最深处88 m,50%以上线路需要按海底隧道真空管道方式建设; 3)B 线全长约106 km,海底平缓,最深处67 m; 4)C 线全长约134 km,最深处66 m,自然纵坡小; 5)D 线全长约173 km,最深处51 m。建议将B 线、C 线作为海底真空管道高铁线路重点方案予以论证和考虑。

Abstract: The scientific selection of submarine channel crossing Bohai Strait is introduced, the concept of submarine vacuum tube of high-speed railway is put forward, and its advantages and disadvantages are analyzed. And then the plane route direction and longitudinal cross-section model of the 4 possible routes, A, B, C and D, between Yantai and Dalian are established according to the sea conditions and topographical and geological characteristics of the Bohai Strait. Finally, the following conclusions are drawn through the study of the comparison among route schemes: (1) It is more economical and ideal to lay submarine viaduct, immersed pipe or subsea shallow burial, which is superior to subsea tunnel. (2) The total length of line A is about 110 km, passing through the deepest sea area of 88 m; more than 50% of the line needs to be built according to the vacuum tube mode of the submarine tunnel. (3) The length of line B is about 106 km, the seabed is gentle, and the deepest point is 67 m. (4) The length of line C is about 134 km, the deepest point is 66 m, and the natural longitudinal slope is small. (5) The length of line D is about 173 km and the deepest point is 51 m. It is suggested that line B and line C should be discussed and considered as the key schemes for submarine vacuum tube of high-speed railway.

Key words: Bohai Strait, cross-sea channel, submarine vacuum tube, high-speed railway route, scheme comparison and selection
