Advance geological prediction and disaster prevention occupies a very important position in the tunnel construction , especially in the construction of some major projects , the accurate prediction of geological and the correct disaster prevention measures to avoid the occurrence of geological disasters has very important significance . However, because any kind of prediction methods have their advantages and disadvantages , and limitations on Geophysical class prediction method also exist multiple solutions of the probe results , the current domestic and foreign advanced geological forecast has not achieved satisfactory results . Therefore, the full use of the knowledge of geomechanics , the proper use and further development of the TSP detection technology is the core content of current advance geological forecast . The only advance geological forecasting and disaster prevention measures organic combination , in order to minimize the construction project inputs and casualties . This paper is divided into two , first advanced geological forecast Xiang'an tunnel , for example , gives the general idea of advanced geological forecast concrete steps . Then the forecast with the actual situation in control , advanced geological forecast organic combination of ideas and content . Practice has proved that the basic theory and guidance , geomechanics detection technology combined with the TSP application of advanced geological forecast of tunnels , more scientific and reliable forecast results . This not only improves the tunnel geological prediction accuracy and speed up the construction progress of the tunnel , tunnel geological prediction for the future but also provide meaningful lessons . Second for geological disaster prevention and management . Part of the geological disaster prevention , Xiang'an tunnel , respectively, to discuss technical measures preventing collapse of the shallow cave segment ; bedrock fissure water treatment measures ; intertidal fault zone , submarine weathering slot preventing collapse outburst prevention measures . Governance section of the geological disasters , Xiang'an tunnel several geological disasters , the analysis of geological disasters , summed up the geological disasters governance measures , provide a useful reference for future disaster prevention efforts .
