비파괴 물성-사질토 지반정수 상관관계 조사 및 평가

Abstract

There are many methods to estimate geotechnical parameters through field tests like SPT and CPT, but these require soil disturbance. Recently, geophysical prospecting is performed using methods to estimate Vs, Vp, and resistivity, but the use of geophysical prospecting to estimate geotechnical parameters is limited due to a lack of correlations between non-destructive properties and geotechnical parameters. In this study, triaxial compression tests were performed to estimate geotechnical parameters for sand and a literature review was performed regarding correlation between non-destructive assessment properties and geotechnical parameters for all soils. Also, a hybrid triaxial compression test system was designed to evaluate the correlations between non-destuctive properties and geotechnical parameters.
