过海、过江(河)隧道线路设计浅析

Analysis on Alignment Design of Sub-sea Tunnels and River-crossing Tunnels

随着我国经济的快速发展,道路交通工程也进入了一个新的世纪。通过对过海、过江(河)隧道的历史、现状进行了叙述,指出了此类项目正在逐步成为方案选择的主要方向。并就工程的线路方案设计进行了详细的阐述,提出了此类项目线路设计的侧重点与其他项目的不同之处,就过海、过江(河)隧道项目线路设计进行了初步分析探讨。

With the rapid development of Chinese economy, road transportation works has entered a new era. On basis of presenting the history and state-of-the-art of sub-sea tunnel s and river-crossing tunnels, the author states that sub-sea tunnels and river-crossing tunnels are gradually becoming the major trend of works alignment selection. The author makes detailed expatiation on the design of works alignments and provides the important aspects of alignment design of such works, as well as the differences between such works and the other works. The author also makes preliminary analysis on the alignment design of sub-sea tunnels and river-crossing tunnels.
