Field Testing of Inclined Cone Penetration
It is expected that the measurements of tip resistance and sleeve friction will be somewhat different between vertical cone penetration tests (CPTv) and inclined cone penetration tests (ICPT). In order to investigate this effect, a field testing program was performed in three different locations with varying soil characteristics in Louisiana. The values of tip resistance and sleeve friction were compared between CPTv and ICPT. The coefficient of lateral earth pressure at rest, K0, indicates the degree of initial stress anisotropy. It was found that, both the tip resistance and the sleeve friction tend to increase for K0 < 1 or decrease for K0 > 1 as the orientation of penetration changes gradually from vertical to horizontal.
