摘要
本文运用扫描电镜（ＫＹＫＹ—１０００Ｂ）对室内配制的黄土状粉土液化的微结构分析表明：粘粒含量为９％的粉土微结构为支架式胶结，在力的作用下，抗液化能力最差。其原因为以支架接触式胶结粉粒的粘土颗粒所起的“润滑作用”所致。此理论为今后进一步研究粉土液化机理提供了重要依据。
In the present paper,remolded loessial silt samples were studied for their microstructure by KYKY-1000B divice in the laboratory.The results showed that types microstructure is supporting texture group and dynamic shear strength of silt is very lowest at Pc=9%,because clay particles around sand has a 'lubricating action'.Meantime it provide the basis of theory for the study of silt liquefaction mechanism the future.
