The Effects of Probe Diameter and Penetration Speed on the Miniature Penetrometer Tests

摘要：

　　The miniature penetrometer tests are often used to investigate the distribution and strength of aggregates in soils.In this work,seven different diameters of probe and three different penetration speeds were used in the miniature penetrometer tests.The results show that: Smaller probe diameter is not suitable for stiffer clay; therefore,determining suitable diametric probes is necessary before conducting miniature penetrometer tests on different types of clay.However,the influence of the probe diameter on penetration can be ignored,if the probe is non-deformed.Faster penetration speed results in larger penetration stress when the penetration speeds are in the range of 8.9 mm/min to 50.5 mm/min.When the probe diameters are in a range of 2.35 to 2.95 mm,the penetration speed will have a significant influence on penetration stress.
