The Application of Ground Penetrating Radar in the Karst Detection of Tunnel Bottom

Abstract:

In order to ascertain the karst development status under tunnel arch, take the appropriate engineering measures according to the different karst state and ensure the tunnel structure safety. Based on the difference electric properties of electromagnetic wave in the different media, for karst development features of large dam tunnel area, applying geological radar, the karst development status under the tunnel arch dam bottom was detected. Geophysical interpretation show the karst of the rock under arch dam bottom develops well and exist karst structure. The tunnel is not safe. In construction, engineering measures such as excavation and backfill are taken. The results show that: the geological radar is a good resolution for karst development situation; the engineering measures adopted are effective.
