物探方法在乌鹅隧道施工中的应用

Application of Geophysical Exploration Method to Wu'e Tunnel Construction

乌鹅隧道位于厦蓉高速贵州境,施工存在的主要工程地质问题是浅埋段软弱围岩、岩体破碎带、软弱夹层、地下水等。上述地质问题致使隧道施工难度及风险性大大增加,隧道施工中多次出现变形坍方。本文针对乌鹅隧道问题,在施工期应用适合的物探方法,较好地预测了该隧道的围岩地质情况,保障了工程施工安全和质量。

Wu'e tunnel is an important construction of Xiarong expressway in Guizhou province. The main engineering geotechnical problems of the tunnel are soft rock in the shallow entrance,broken rock,soft rock layers and groundwater. Many problems such as big deformation and collapse often happened in the tunnel construction,which made the tunnel construction difficult and the risk increases greatly. The author conducted the applied research of more than one geophysical exploration methods in the tunnel and reached some conclusions and solved the complex engineering geological problems of the tunnel.
