Study on safety monitoring and forecasting of Qingping tunnel exit based on image processing technology

摘要

In order to ensure the construction safety and schedule of Qingping tunnel exit, the paper forecast the geological conditions and abnormal prediction of the two holes in front of Qingping tunnel exit by using TSP, then according to the geological detection image data, combined with geological data and working face surrounding rock geological reveal the interpretation. The results show that, the rocks of the Qingping tunnel exit is crushed, more karst structure is development and part of the underground water is rich, where potential safety hazard as gushing and collapse exists in the construction, should take corresponding measures as soon as possible.
