摘要
基岩裂隙水的富集对隧道施工安全及建成后的运营管理造成严重威胁。对基岩裂隙水的赋存情况进行准确及时的预测,可有效降低隧道地质灾害的发生几率,确保隧道施工安全。依托宜巴高速公路郑家垭隧道,结合掌子面YK129+843处涌水情况,研究了岩体赋存裂隙水情况下深度偏移图、反射层提取图以及岩体物性图中岩石参数曲线的变化趋势。研究表明TSP超前地质预报方法对基岩裂隙水赋存情况的探测结果比较准确,对类似地质条件下的超前地质预报工作具有一定的借鉴意义。
The enrichment of bedrock fissure water poses a serious threat to safety and management of tunnel construction. Forecasting of bedrock fissure water accurately and timely can lower the probability of geological hazards and guarantee the tunnel construction＇ s safety. The depth migration, reflector extraction, physical properties of rock mass and tendency of parametric curves with bedrock fissure water occurrence, especially the situation of water inflow at YK129 ＋ 843, was analyzed and studied on Zhengjiaya tunnel of the Yiba expressway. It is proved that detection result of bedrock fissure water by TSP advanced geological prediction is comparatively accurate, and it has certain ref- erence meanings to advanced geological prediction for the similar geological conditions.
