| 摘 要： | “台湾海峡隧道”这一伟大工程，由构想到正式调研，历经许多过程，存在许多疑难。台湾海峡的海底地质情况较复杂，且是一个多地震地区，在当前技术条件下，到底能不能修海底隧道，引起两岸许多学者的关注。根据当前已经获得的各种科技成果，在海峡北部的台湾桃园县沿海地区，分布着厚度较大、岩层水平、并已固结的第四纪砂页岩，形成良好的承力层和隔水层。海峡西端的福建平潭岛是大片的花岗岩分布区，场地开阔，是理想的隧道终端。因此，可以初步认为，从平潭到新竹一线，地质及地震条件较为稳定单一，可以考虑作为首选海底隧道线路。

| Abstract: | The Taiwan Strait Tunnel (T.S.T), as a great project, has been proposed for a long time and met many challenges from the beginning of the feasibility study that has attracted attentions among scientists in both sides of the Taiwan Strait. The key question is whether this undersea tunnel could be constructed with present technologies under such complex geologic and seismologic conditions. Results of current research indicate that sea floor in the north of the Strait along coast of Taoyuan county of Taiwan is covered by the late Tertiary to Quaternary sandy shale and shale with a thickness of more than 300m without large fault-belt, which could serve as a good bearing and impermeable layer. Along the coast of Pingtan Island, Fujian in the west of the Strait, there is an area with vast distribution of granite, which is ideal for the construction of the tunnel terminal. We therefore suggest that the shortest line with a distance of 126km from Pingtan Islan, Fujian to Hsinchu, Taiwan should be considered as the undersea tunnel line for its simple and stable geological condition. |
