| Abstract | ||
| The methods for estimating in-situ hydraulic conductivity (khp) and coefficient of consolidation (chp) in the horizontal direction from piezocone penetration and dissipation test results have been investigated using test results at two sites in Saga, Japan. At the two sites the laboratory values of hydraulic conductivity (kv) and coefficient of consolidation (cv) in the vertical direction are also available. Comparing khp with kv and chp with cv values, suitable methods for estimating khp and chp values are recommended. For the two sites, where khp ≈ kv and chp ≈ 2cv. It is suggested that the estimated values of khp and chp can be used in engineering design. | ||
