Abstract: The paper describes the application of seismic reflection method in the advance forecast of Miaoshan tunnel of Huaixin express highway and introduces the features of this geological advance forecast method that is commonly used in tunneling. Advance geological forecast can provide reliable geological data and information for a rapid tunneling, preparation of support materials and effective prevention of disaster accident. The effectiveness of the seismic reflection method in advance forecast is illustrated.

Key words: Miaoshan tunnel, Seismic reflection method, Advance forecast
