台湾海峡隧道工程的若干工程地质问题与选线方案探讨

ENGINEERING GEOLOGICAL PROBLEMS OF THE TAIWAN STRAIT TUNNEL PROJECT AND PRELIMINARY STUDY ON THE ROUTE PLAN

对台湾海峡的地质状况了进行了分析 ,作者认为 ,台湾海峡的工程地质条件复杂 ,地震、活动断裂、岩土体稳定性、海底底床活动性等是隧道工程将遇到的主要工程地质问题。隧道的线路选择应进行全面、深入的技术、经济比较。

Engineering geological conditions are rather complicated in the Taiwan Strait. The major engineering geological problems to be encountered by the proposed Taiwan Strait Tunnel (TST) Project are earthquakes, actives faults, stability of rock and soil masses, bedform activities, etc., and those problems are studied here preliminarily. Tunnel route selection should be carried out based upon comprehensive technical and financial analysises. Two routes are proposed and discussed: One is from Pingtan to Hsinchu, and the other is from Xiamen to Jiayi through Kingmen and Penghu Islands.
