Results show that degree of compaction, compaction water content and saturation state of compacted soil have influence on cohesion and Angle of friction of clay, thereby on the shear strength of clay.
试验表明，压实度、压实含水量及土体饱和状态对粘聚力和内摩擦角有影响，从而使抗剪强度也受到三因素的影响。
Influenced by cohesion, the water head difference in silt is more than that in sand when seepage failure takes place. Influenced by piles, the water head difference of seepage failure also increases.
受黏聚力的影响，粉土破坏时的水头差较砂土大，同时基桩的影响也会增大破坏时的水头差。
The cohesion and internal friction angle increase with the increase of compaction under the same water content.
在同一含水率下，黏聚力和内摩擦角随试样压实度的增加而增大；
