【Abstract】 This paper describes the results of testing on the meohanical properties of highly com- pressible silt.The testing terms which were conducted are cheifly as following: 1)the relation between the time and the coefficient of lateral pressure at rest of un- disturbed silt under the vertical pressure; 2)the magnitude of the coefficient of lateral pressure at rest of undisturbed silt; 3)the effect of pre-loading on the coefficient of lateral skelton pressure at rest; 4)the relation of void ratio of undisturbed silt with vertical pressure and the relation of void ratio with the sum of tri-axial stresses under the repeated pre-loading condition; 5)the relation between the coefficient of tolal lateral pressure at rest of disturbed silt and water content; 6)the cappillary pressure of silt and its relation with water content; 7)the relation of lateral pressure of silt with time,unit dry weight and water content due to absorbing water.更多还原
