Energy Correction and Use of Standard Penetration Test N Value
표준관입시험 N값의 올바른 보정 및 사용
Abstract
Due to the variation of equipments and test procedure, level of energy transferred to split spoon sampler varies and thus measured N value. Since the properties and parameters are estimated from empirical correlations related to N value, the correction of N value with respect to specific energy level is essential. Factors affecting N value are discussed and the results of previous studies on energy correction of SPT N value is reviewed. Part of results from joint research works with KHC are presented and the range of energy levels for the hammer and release system typically used in Korea is suggested.
