Abstract:

To study the change law of shear strength, cohesiveness, internal friction coefficient and compression load of ectopic fermentation mattress under different moisture content, the soil mechanics test method was used to determine the relevant parameters of five different water content of cushion. The results show that the shear strength and the angle coefficient of internal friction increase with the rise of the water content when the water content of the cushion is 29.22%~36.13%. When the moisture content is 45.55%~61.11%, the shear strength and the angle coefficient of internal friction decrease with the increase of moisture content. The cohesiveness does not change obviously with the change of water content. The compression load of cushion increases with the increase of loading time, and the increasing amplitude rises gradually.

Key words: ectopic fermentation bed, bedding, shear strength, cohesiveness, coefficient of internal friction, the compression load
