This paper presented a method to estimate the consolidation yield stress of compacted soil with an unsaturated soil mechanics, especially considering the effect of matric suction. Then two kinds of experiments were conducted. One is a series of static compaction tests to monitor the matric suction, and the other is a series of consolidation tests on compacted soil without soaking. The results indicate that it is possible to derive the distribution of matric suction on compaction curves and to hypothesize the changes of the void ratio depending on the matric suction in the consolidation tests. With this experimental results, a new method was introduced to estimate the consolidation yield stress of compacted soil including compaction curves.
