【摘要】 本文针对青兰高速公路邯郸至涉县段某隧道右线施工掌子面前方围岩情况及隧道拱顶上覆岩土体埋深特点,采用TSP超前地质预报系统进行长距离预测,采用美国SIR-20型地质雷达进行短距离验证,采用拉脱维亚的Zond-12e型地质雷达对隧道拱顶上覆岩土体性状及分布情况进行探测。3种物探方法的综合利用,弥补了现有单种物探方法的不足,使探测结果用于指导隧道施工更加科学合理。更多还原

【Abstract】 In view of the condition of adjoining rock at the front of working face of right line construction of a certain tunnel for Qinglan Expressway,the paper adopts TSP advance geological prognosis system to detect long-distance pre-measure,and adopts USA SIR-20 type geological radar to detect short distance validation,and adopts Latvia Zond-12e geological radar to detect the properties and distribution of rock cover soil above tunnel vault The comprehensive utilization of three kinds of geophysical method makes up for the deficiency of existed single geophysical method,making the detecting result for the direction of tunnel construction more scientific and reasonable.更多还原
