| Sandfill at reclaimed sites is usually formed by more than one placement method. Reclaimed sandfill often shows highly variable profiles and the cone penetration test is most commonly used for site characterization. Correlations between cone resistance and geotechnical parameters for sand are influenced by in-situ stress level and it is important to incorporate stress level effect. In this study, cone penetration tests were performed at several elevations from the top of a 10m high surcharge, which was later removed step by step. In order to establish more reliable correlations between cone resistance and geotechnical parameters for sand, different ways of normalizing cone resistance by the corresponding in-situ vertical stress were investigated. |
