Abstract
In order to find the relationship between the cone resistances measured in horizontally and vertically aligned cone penetration tests, a test series has been performed in a 2 m. diameter rigid wall calibration chamber using a 36 mm. cone. This calibration chamber contains an unsaturated uniform sand, which can be prepared at different densities. It is found that the horizontal cone resistance is higher than the vertical cone resistance at a given point, whilst the side friction is lower horizontally than vertically. A simple cavity expansion model is used to explain the ratio of horizontal over vertical cone resistance.
