The influence of some parameters on penetration resistance of a silty soil

Abstract

    This paper presents the influence of some parameters on penetration resistance of a silty soil such as dry density, compaction water content and prior immersion time. Obtained results show an increase of penetration resistance with dry density, decrease with compaction water content and prior immersion time which leads to the change of suction of soil caused by the change of infiltration of water. In the case of a low dry density and a long prior immersion time, the influence of the compaction water content is not significant. The effect of suction diminution is more and more weak over time of prior immersion, and it plays a minor role for the soil having a high water content or a low dry density.
