수중에서 사용가능한 굴착공 벽면거칠기 측정 시스템(BKS-LRPS)의 굴착공 내 혼탁도 보정에 관한 연구 = Turbidity Calibration of Borehole Roughness Measurement System (BKS-LRPS) Usable in Water

다국어 초록 (Multilingual Abstract)

Based on recent studies, the side resistance of rock socketed drilled shafts was affected by unconfined compressive strength of rock, socket roughness, rock types and joints, and initial normal stress. Especially, the socket roughness was affected by rock types and joints, drilling methods, and diameters of pile. In this study, a new roughness measurement system (BKS-LRPS, Backyoung-KyungSung Laser Roughness Profiling System) usable in water was developed. Based on the laboratory model tests, an EMD (Effective Measurement Distances) according to various turbidity was proposed as .
