【摘要】 目前在隧道掌子面地质超前预报中应用最广泛的方法有红外探水法、地质雷达法和TSP超前地质预报。实际工作中,红外探水法主要对隧道掌子面前方有无含水做定性评价,地质雷达法为短距离定量精确预报,TSP超前地质预报方法主要用于长距离预报。这三种方法若能合理组合,可以相互佐证,提高预报结果的准确性,现在综合物探方法已经成为确保隧道施工安全必不可少的手段。通过这三种物探方法在某隧道超前地质预报中的实施情况可知,综合物探方法取得了很好的预报效果,给施工单位提供了有效而科学的指导。更多还原

【Abstract】 The methods of the infrared water exploration,the geological radar and the TSP geological leading forecast are currently used in engineering practice.The method of infrared water exploration is used for evaluating the hydrous case or non-hydrous case in front of the workaround,and the method of geological radar is used for the short distance precise forecast,and the system of the TSP geological leading forecast is used for the long distance forecast.The effective combination of these methods could be proved mutually and improve the accuracy of exploration results.The integrated geophysical prospecting method is the necessary method to ensure the safety of tunnel construction in the leading tunnel geological forecast.The combination of the said three kinds of forecast methods get the precise prediction results in the geological leading forecast of certain tunnel,which provide the effective scientific guidance to the engineering construction.更多还原
