云台山隧道是山西省阳(城)翼(城)高速公路的重要控制性工程。隧道洞口区围岩以石炭纪太原组灰岩、泥岩、砂岩和煤系地层为主,为探测开挖工作面前方围岩工程地质和水文地质情况,获取详实可靠的地质信息,并有效地指导施工,本隧道施工采用TSP超前地质预报技术分析推断掌子面前方的地质情况,为制定施工方案和措施提供可靠的参数,避免或最大限度的降低施工过程中突泥、涌水、塌方、煤系地层(采空区)等灾害事故发生,从而不受或少受损失、为隧道在安全条件下实现快速施工、减小风险创造条件。
The Yuntaishan Tunnel is an important controlled project of the Yang (City) Wing (City) Expressway in Shanxi Province. Surrounding rocks in the tunnel area are mainly composed of limestone, mudstone, sandstone and coal measures in the Taiyuan Formation of the Carboniferous. In order to detect the geology and hydrogeology of the surrounding rock in front of the excavation worksite, detailed and reliable geological information is obtained and effectively guided Construction, tunnel construction using TSP advanced geotechnical forecasting technology to infer the front of the face of geology, provide reliable parameters for the development of construction programs and measures to avoid or minimize the process of mud, gushing water, landslides, coal Stratum (goaf) and other disasters occurred, so as to suffer less or less damage, to create conditions for tunnels to be constructed quickly under safety conditions and to reduce risks.
