Schmidt hammer 반발지수로 울산지역 퇴적암의 공학적 특성을 추정하기 위한 연구 = A Prediction of Engineering Properties of Ulsan Sedimentary Rocks with Schmidt Hammer Rebound Number

다국어 초록 (Multilingual Abstract)

A study has been made of the Schmidt hammer rebound test for the estimation of engineering and physical characteristics of sedimentary rocks. As there is no universal formular for the estimation of rock strength due to geological conditions, in this study only sedimentary rocks are adopted to testing. The aim of study is to make the information more meaningful and useful for engineers and contractors by providing rapid, cheap and easy method. The obtained parameters were correlated and regression equations were established among Schmidt hammer rebound number, uniaxial compressive strength, tangent Young’s modulus, indirect tensile stress, water absorption and porosity of rocks with high coefficients of correlation with each other.
