The topographic form, the meteorological and hydrological conditions, lithology, geological structure and the distribution of fault zone of the Taiwan Strait were analyzed. The schemes of bridge and tunnel, schemes of road and railway tunnels, schemes of tunnel bit of the Taiwan strait cross-sea channel were compared. The design schemes of the tunnel longitudinal section and the cross section were given; meanwhile, the technical feasibilities of the Taiwan Strait railway tunnel were analyzed. The construction of the channel of the Taiwan Strait can improve the railway network and the highway network, and will trigger a new round of investment and construction boom, moreover, it plays a huge role in promoting the development of cross-strait economic.%分析了台湾海峡的地貌形态、气象及水文条件、地层岩性、地质构造及断裂带的分布;对比了台湾海峡越海通道的桥隧方案、公路与铁路隧道方案、隧道线位方案,并给出了隧道纵断面和横断面的设计方案;分析了台湾海峡铁路隧道技术的可行性.台湾海峡通道的修建可完善中国铁路网和高速公路网,也会引发新一轮的投资建设热潮,可对两岸经济发展起到巨大的推动作用.
