The effect of asymmetrical characteristics of seismic loads on the soil deformation is pointed out by using the triaxial dynamic tests. The test results indicate the asymmetrical characteristics of PGA have the significant effect and in some cases play the dominant role. Using the records of 287 earthquakes above the magnitude 5 the feature of the symmetry ratio of PGA is described and the its calculation formula is presented。The statistic results indicate that the asymmetrical characteristics of the earthquakes loads are obvious and the asymmetry ratio of PGA is 1.0－3.3, 1.3 on average. The probability of the asymmetry ratio of PGA is 30% for 1.2－1.4 and 60% for 1.1－1.5. The average asymmetry ratio of PGA is 1.4－1.2 from the magnitude 5 to the magnitude 8 and slightly decreases with the increasing of the magnitude.
