In this paper, a series of experiments, researches and discussions have been conducted on some mechanical properties of highly compressible sludge. It mainly includes the following items: 1) the relationship between the total static side pressure coefficient and the time of the original sludge under the vertical pressure; 2) the size of the lateral pressure coefficient of the original sludge; 3) the effect of precompression on the static pressure coefficient of the skeleton 4) The relationship between the void ratio and the vertical pressure of the original silt under multiple preloading conditions, and the relationship between the porosity ratio and the sum of the triaxial stresses; 5) The relationship between the total static pressure coefficient of the disturbed sludge and the water content; 6 ) The capillary pressure of the sludge, its relation to the water content; 7) the lateral pressure of the sludge when soaked by water, its relation to time, its relation to dry bulk density and its relation to water content.
