【摘要】 在某深埋、特长隧道施工过程中,为能够更准确地预报地下水,特引入钻孔雷达和BEAM电法预报方法。以典型洞段的预报成果为例,将其与传统方法预报成果进行对比分析,对钻孔雷达和BEAM电法运用的可行性与合理性进行了探讨。实践表明,采用钻孔雷达和BEAM电法探测技术对隧道掌子面前方的不良地质情况,尤其是含水情况具有较好的预测结果。更多还原

【Abstract】 In construction process of a deep embedded and very long tunnel,in order to accurately predict ground water level,boring radar and BEAM electric prediction method are introduced.Taking typical prediction achievement as example and comparing with the prediction achievement by traditional prediction method,the feasibility and reasonability of using boring radar and BEAM electric method are investigated.The practice demonstrates that the prediction to adverse geologic condition in front of the heading face by boring radar and BEAM electric method,especially to water-holding condition,is satisfied.更多还原
