摘要
在隧道超前地质预报中,较常用且预测准确性较高的预测手段是采用地质雷达对开挖掌子面前方的不良地质情况进行预测。以广大双线铁路下庄1号隧道为例,通过现场的数据采集以及后期的数据优化处理,可以生成地质雷达图像来较直观地预测掌子面前方的地质情况。预测结果与现场开挖验证情况较为吻合,表明通过地质雷达数据点的优化处理提高了对开挖掌子面前方的地质情况进行预测的准确性。
Using the geological radar is a commonly used forecast method with high forecast accuracy in the advance geological forecast of tunnel. Theadverse geological condition in front of excavation tunnel face can be forecasted. Taking Xiazhuang#1 tunnel of Guangtong-Dali Double-track Railway for an example,through field data acquisition and post data optimization and processing,the geological radar image can be generated to more intuitively forecast the geological condition in front of the tunnel face. The forecast results are consistent with the field excavation verification condition. This means the optimization and processing of geological radar data point can improve the accuracy of the forcast of the geological condition in front of the excavation tunnel face.
