Cone penetration test is often used for field investigation of foundation. It is also implemented to measure cone index of compacted soil. Cone index of soil depends on the strength of the soil. Each cones used in the above penetration tests have different diameters. In this study, six kinds of cones were used in penetration tests in laboratory, which have three different cone diameters and two different cone top angles respectively. Those tests revealed that : 1) cone which have the same top angle and different diameters show almost the same q_c. 2) cone which have different top angles and the same diameters show the same q_c, whereas they show different q_cs during the penetration process. 3) a correlation between cone index q_c and unconfined compressive strength q_u in a certain soil can be expressed as shown by the following formula. q_c[numerical formula]5×q_u
