| 摘 要： | 引水发电隧洞由于施工、地质原因，可能存在混凝土衬砌与围岩脱空、回填灌浆桨量不足以及爆破松动和开挖时崩塌等问题，本文针对施工中的这些问题运用声波反射法、超声波法和钻孔雷达法对引水隧洞进行物探综合检测方法的原理及运用实例作简要介绍。

| Abstract: | Because of construction or geologic factors, there may be problems of separation between concrete lining and surrounding rock, insufficient backfill grouting, loosed rock by blasting and landslip by excavation in the power conduit tunnel. Directed at these problems in construction, the paper introduces the principle and practice by using sound wave reflection method, ultrasonic method and borehole radar method for the integrated geophysical checking of power conduit tunnel. |
