Abstract Abstract：Research purposes： Most of buried fault is located at plain area where surface is covered by loose deposit. Usually, the fault aggravates the damage of earthquake and has great potential safety hazard for the railway engineering safety. Shallow seismic reflection is a major method for buried fault exploration. In this paper, the acquisition and processing technology of high resolution shallow seismic reflection are analyzed and summarized by several successful application of this method, to solve the problem of precise detection for buried fault in railway engineering.
Research conclusions: According to the research on acquisition and processing technology of high resolution seismic reflection, in order to increase the application effects，it should take the following measures:(1) Adopt the observation system of small group interval, small shot distance and high folds. (2) Adopt small offset and far shot - geophone distance. （3) Choose the suitable site and seismic source. （4) The equipment should have strong capacity of resisting disturbance. (5 ) Use suitable seismic processing technology. (6) The research results have a certain guiding significance for application of high resolution seismic reflection in fault exploration of railway engineering.
