Micro-analysis of anti-liquefaction of silt

Through analysis of the SEM experiment on the retem pering silt with di fferent clay contents and at different times, the writer introduces the variatio n law of silt's micro structure and the relationship between silt's micro stru ct ure and it's anti liquefaction. Through analyzing the silt's micro photo, the wr iter draws the conclusion that the micro structural characteristics of the silt with natural grains of clay varies when it's clay contents amount to Pc=9%, which is one of the turning points where the silt's characteristics change.
