| 摘 要： | 研究隧道稳定性时,水对隧道的影响有时起到很重要的作用。对隧道进行安全稳定计算时应当把水的作用考虑进去,进行流固耦合分析,这样才能与工程实际情况相吻合。以清水隧道为研究背景,进行了隧道流固耦合的研究分析,分析了不同工况条件下隧道的稳定性,计算结果与现场工程实际状况吻合较好。

| Abstract: | Water sometimes is very important in the tunnel stability analysis.So water factor should be considered if analysis the tunnel stability that is hydraulic coupled analysis.Through hydraulic coupled analysis for tunnel,the result can be close to the real.As now,finite difference nethod is often used for hydraulic coupled analysis;the most common software is FLAC.In the paper,the Qingshui railway tunnel stability is analyses by finite difference method,three cases is researched,the calculating result is very well to the real appearance. |
