LAWS OF CONSOLIDATION, CREEP STRAIN AND STRESS RELAXATION OF SATURATED SOFT CLAY

This paper studies the law of consolidation and creep strain of saturated soft clay subjected to static and repeated loads under drained and undrained conditions. The following results are obtained from the tests: (1) The coefficient of earth pressure at rest is a decreasing function of time under drained condition; (2) The saturated soft clay creeps under both drained and undrained conditions. There is a linear relation between the amount of stable creep and the square of time; (3) The speed of creep is greater under repeated loads than that under static loads; and (4) The coefficient of earth pressure at rest increases with time when the soil shear stress relaxes under drained condition. The law of soil shear stress relaxation is also presented.
