摘　　要：为克服单一超前地质预报技术存在精度不足、准确率不高的问题,提出采用短、中、长预报距离相结合的综合超前地质预报体系。该方法对牡佳高铁某隧道里程段穿越断层的预报信息,得到开挖揭示的成功验证。结果表明:地质调查法、超前水平钻探法和TSP地震波反射法相结合的预报方法,对隧道内不良地质的分布、规模和围岩工程地质以及水文地质信息的预报有极高的准确度,为工程安全建设提供真实有效的地质资料,对各种复杂地质环境下超前地质预报方法在隧道工程中的选择和运用具有实践参考价值。In order to overcome the lack of precision and low accuracy of the single advanced geological forecasting technology,a comprehensive advanced geological forecasting system combining short,medium and long forecasting distances was proposed.The method is used to predict the fault crossing of a tunnel length section of Mujia high-speed railway,and the excavation disclosure is verified successfully.The results showed that the prediction method combining geological survey method,extended horizontal drilling method and TSP seismic wave reflection method has high accuracy in predicting the distribution and scale of adverse geology in the tunnel and the engineering geology and hydrogeology information of surrounding rock,and provides real and effective geological data for the safe construction of the project.It has practical reference value for the selection and application of advanced geological prediction methods in tunnel engineering under various complex geological environments.
