Abstract

The evaluation of soil properties in the local area has become important for understanding the subsurface spatial variability. The objective of this study is the development and application of new apparatus, Cone Resistivity Penetrometer (CRP), which measures the cone tip resistance, sleeve friction and electrical resistivity to evaluate the soil behaviors. The CRP developed is 15 mm in diameter with a projected area of 1.76 cm 2. The strain gauges are used to measure the cone tip resistance and sleeve friction. The cone tip resistance is effectively separated by using a friction sleeve. The electrical resistivity module, which consists of two electrodes and insulator, is installed at the cone tip to increase its resolution with minimum disturbance during penetration. The application test in the field is conducted and the measured results are compared with those by the standard piezocone test. The results show that the CRP, which measures cone tip resistance, sleeve friction and electrical resistivity, clearly evaluates the subsurface profile. This study suggests that the CRP may be a useful tool for the evaluation of the subsurface spatial variability during in-situ penetration tests.
