This paper examines a new method of advanced geological predictionwhich overcomes the difficulties found in other usual methods.ln this paper,we first briefly introduce the characteristics of the usual methods of advanced geological prediction.and then,we put forward a comprehensive advanced geological prediction method which on the basis of geological survey,and combine with physical exploration methods and advanced drilling methods,and we also set up reasonable forecast process.it is the first time to use Google Earth software into tunnel advance geological prediction.And by using comprehensive advance geological prediction me-thod,we have successfully predicted the adverse geological conditions in front of DA-Pingshan tunnel face.Thisverify that the comprehensive advanced geological prediction method is accurate and feasible in practice.And it alsoprovides a train of thought for the similar tunnel advance geological prediction in future.
