Abstract Fault influenced zone is one of the key factors in site selection and design for high-level radioactive waste repository. Field survey and chart analysis were used to obtain the relationship between the fault distance and mean length of traces，the midpoint density of both sides of fault. When the distance increases，the mean trace length increases and the midpoint density decreases. The correlations obey a negative exponential function. When the distance exceeds the width of the fault influenced zone，the mean trace length and the midpoint density fluctuate at a certain value. Accordingly，both sides of the fault can be divided into two regions：serious influenced zone I and influenced zone II. The width of the maximum influenced zone and the distribution are markedly different among different fault types，the one of the normal fault is the smallest，the one of the strike-slip fault is the second，and the one of the reverse fault is the largest. Meanwhile，the influenced zone of the strike-slip fault shows a symmetrical distribution，and the normal and reverse faults show asymmetrical distribution. The width of fault influenced zone and the length of fault obey a power function approximatively.
