The investigation was made to estimate the consolidation yield stress of cohesive soils by using sounding tests. The allowable stress of a ground was considered in taking account of the allowable settlement. It was found that the ratio of the undrained shear strength to the effective vertical pressure for normally consolidated soils under K_0 consolidation can be determined approximately as a constant of 0.375 irrespective of plasticity index. The consolidation yield stress of overconsolidated soils subjected to K_0 consolidation was estimated from upper and lower bounds simulated by the proposed model. Similarly, the consolidation yield stress of incompletely consolidated soils was predicted. Furthermore, an analytical method to calculate the allowable stress was proposed for the multi-layered ground.
