摘要
深埋隧洞由于埋置深，覆盖层巨厚，具有高地应力、高渗水压力等特点。对深埋隧洞开挖工作面前方的的不良地质、特别是大涌水进行准确的超前预报，是及时采取措施，避免灾害发生，减少工期延误，保证施工安全的重要措施。
A deep tunnel has thick overburden with high stress and water pressure. Accurate forecast of large water pour taking place in adverse geology in front of excavated face may help take timely measures to avoid hazard and minimize delay.
