Effect of Duration of Confinement and Its Affecting Factors on the Low-Amplitude Shear Modulus ($G_{max}$ ) of Soils
토질 최대전단탄성계수($G_{max}$ )에 미치는 시간지속효과 및 그 영향요소에 관한 연구
Abstract
Dynamic Shear modulus (G) is one of the imfortant dynamic soil properties to estimate the response of soil to dynamic loading. Problems in engineering geo1ogy practice the require the knowledge of soil properties subjected to dynamic loadings include soil-structure interaction during earthquakes, bomb blasts, construction operations, and mining. Although the dynamic shear modulus (G) is a time-dependent property, G change with time is often neglected. In this study, the effect of duration of confinement and its affecting factors (previous stress and strain, particle size and sustained pressure, and plasticity index) on the low-amplitude shear modulus (
동적 하중을 받는 지반반응 평가시 필요한 가장 중요한 변수 중에 하나가 지반의 전단탄성계수(G)이다. 지반의 동특성은 시간에 따라 변화하게 되는데, 이 점은 흔히 간과되어져 왔다. 이번 연구를 통하여 일정구속압에서 시간에 따라 변하는 토질 최대전단탄성계수(
