摘要
西南某铁路隧道全长8.5km,工程地质条件复杂,软岩变形、岩爆及涌水量的预测是本隧道勘察中需要解决的重要问题之一,通过在各勘察阶段综合采用遥感判释、现场调绘、综合勘探等方法,对隧址内工程地质条件进行了详查,查明了对隧道有影响的构造,地应力,地下水等的性质,为隧道的设计施工提供了依据.
A railway tunnel in southwest China is 8.5 km long,with complex geological conditions.The forecast of soft rock distortion,rock burst and water yield is one of the most important problems in the geotechnical investigation of the tunnel.Based on remote sensing,survey and reconnoitre in various phases,the geological conditions of the tunnel are determined.The faultage of the tunnel,the stress in the earth and the water under the earth are analyzed,which would provide a basis for the design and construction of the tunnel.
