摘要
通过对不同粘粒含量和不同时间情况下的重塑粉土进行扫描电镜的实验分析 ,初步了解了其在不同粘粒含量下以及时效下的微观结构的变化规律 ,以及粉土的微观结构与其抗液化性能之间的关系。通过对粉土微观照片的分析 ,得出结论 :含天然黏土颗粒的粉土 ,其微观结构特性在黏粒含量为Pc=9%附近发生变化。即黏粒含量Pc=9%为粉土土性变化的一转折点。
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.
