Abstract In Xi'an City, there are many disadvantages for ground fissure exploration, such as the human's strong influence on environment and the intense background noise interference. In this study, good result was obtained by adopting the controllable vibrator technique and unique data processing technology. Through selecting the optimal working parameters and employing the appropriate measures for suppressing noise, the authors ensured the high quality of the exploration data. In the shallow seismic data processing process, besides the conventional dataprocessing technology, the authors put forward the corresponding technical processing countermeasures for such interferences as vehicle interference, electrical interference, strong energy interference and curve correction. Using the new method of ground fissure exploration, the authors improved the data precision and made a breakthrough in the highinterference fissure exploration under urban conditions. The results also provide reliable geophysical data for studying the formation mechanism of the fissures in Xi'an City.
