ABSTRACT
This paper presents the investigation of influence of matric suction on unconfined compressive strength of clayey soils with different sand contents. The matric suction within clay samples with sand contents of 0, 20 and 40 percent was applied using the suction chamber. The results show that the unconfined compressive strength increased with increasing matric suction for the matric suction range less than 50 kPa but decreased with increasing matric suction for the suction range greater than 50 kPa. The results also show that the unconfined compressive strength increased with increasing sand content for all values of matric suction. Furthermore, the values of unconfined compressive strength normalized by matric suction for the samples with different sand contents trend to converse to each other at high value of matric suction.
