摘　　要：土体的微观表面特征试验对土体的宏观力学性质及细微观物理化学性质具有重要影响。用低温氮气吸附法对杭州下沙的土体进行测试,分别测得典型黏土、典型粉土的比表面积和最可几孔径,并对试验结果进行分析,从微观上验证了土体的物理状态特性。试验结果可以作为沿海围垦施工中宏观地质勘察的参考依据。Test of microscopic surface characteristics is important for soil mechanical property and physic chemical property.Low-temperature nitrogen adsorption method is used to detect the soil of microscopic surface in Hangzhou Xiasha,and specific surface area(SSA)and most probable pore size of clay and silt are gotten by the text.The text,verify the physical condition of soil,and the result has important value to similar geological survey.
