Abstract：Compared to the normal road or railway tunnels，metro passed through the stratum over the road，so that the metro advanced prediction(mainly geophysical class prediction) implementation can be divided into two parts：prediction inside and outside the tunnel. However，due to shallow depth of the metro and many factors of interference，it?s need to use the comprehensive advanced prediction. By analyzing the metro characters under the karst geological conditions，using the advantages of ground penetrating radar(GPR) and resistivity tomography，a comprehensive prediction method is proposed to carry out GPR forecasts inside and carry out the forecasts of the combination of resistivity tomography and GPR method outside；then through an engineering application，a detailed analysis of the implementation of comprehensive and comprehensive forecasting methods is made to prove that the comprehensive prediction method is effective for metro advanced prediction under the conditions of karst geology.
