통계적 기법에 의한 낙동강하구 점성토 지반의 피에조콘 계수 산정

Recently, the importance of investigation for soft ground has been raised, so that various techniques of the investigation for soft ground are being introduced and applied. In particular, Piezocone penetration test has been utilized frequently home and abroad to identify many features of grounds precisely and gain various results in accordance with dividing strata and depth constantly by measuring continuously. In this study, to identify some features of soft clays distributed in the estuary of Nakdong river, researchers conducted field tests and laboratory tests with boring tests, and analyzed and compared with Piezocone penetration test. In addition, credible Piezocone factor of communities of subjects for this study was estimated to analyze some features of undrained shear strength of clay and calculate Piezocone factor compared with corrected cone resistance and apply some statistical techniques to estimated Piezocone factor.
