Scheme comparison of Qiongzhou strait railway tunnel
Tan Zhongsheng1、Wang Mengshu1、Luo Shixiang2
The construction of the Qiongzhou strait tunnel will not only meet the requirements of the straits' passenger and cargo traffic,but also the needs of national defense, and the constructed tunnel will play a huge pulling role in Hainan´s economic development.Comparing with the similar projects abroad, the preliminary work of Qiongzhou strait tunnel was very urgent and needed a long time, because of enormous workload of research, complex technology and difficulties. Based on the study of meteorological, hydrological, geological data and other information of Qiongzhou strait tunnel, the bridge and tunnel schemes are simply compared, which indicate that the tunnel scheme is suitable, moreover, the shield tunnel scheme for line Ⅱ is better than others. After compared the shallow tunnel with deep tunnel schemes of line Ⅱ, the shallow tunnel using shield method scheme is proposed. As highway tunnel had many technical problems, and project costs and operating costs are very high, therefore, the railway tunnel plan as the preferred option is feasible, and cars could pass through the tunnel by shuttle trains.
