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 the construction safety of the tunnel and the operation and management after its completion. Accurate and timely prediction of the occurrence of bedrock fissure water can effectively reduce the risk of tunnel geological disasters and ensure the construction safety of the tunnel. Based on the YK129 + 843 gushing water of the Yiban Expressway, based on the Zhengjiaya Tunnel on the Yiba Highway, the variation trend of the rock parameters curve in the depth map, the reflection layer and the physical map of rock mass were studied. . The results show that the TSP advanced geological prediction method is more accurate for detecting the occurrence of bedrock fissure water and is of certain reference value to the advanced geological prediction work under similar geological conditions.
