摘要
自从1936年第1条海底隧道——日本关门隧道开始建造以来,世界各地已有近百条海底隧道相继建造。在特殊的环境地质条件下,建造海底隧道无疑是最安全经济、路线最短的方案。但海底隧道的设计与施工还有许多技术问题丞待解决。结合我国拟建厦门海底隧道的工程实际,从数值模拟分析的角度,研究了海底隧道的稳定性与隧道顶板厚度的关系,并结合世界上己建海底隧道的工程经验,给出了厦门隧道的最小安全顶板厚度。
Since the first subsea tunnel——Kanmon tunnel was built in 1936 in Japan,nearly one hundred subsea tunnels have been constructed.Under special environment and geological conditions,subsea tunnel is the safest and most economical scheme.But there are still many problems needed to be resolved.The relationship between minimum thickness of rock cover and tunnel stability is studied by numerical method,combined with the engineering practice of Xiamen subsea tunnel.The minimum safe rock cover thickness is found for the given case.
