Measurements of Socket roughness and Vertical Offsets for Large Foundations

대형기초의 굴착공벽면 거칠기 및 연직도 측정

Recently, construction of high-rise buildings have been increased all around the world, and their foundation are designed to carry heavy loads form superstructures. For this reason, the use of drilled shafts have been increased, and the proper understanding of drilled shafts have been issued, especially for socket roughness and vertical offsets. In this study, the BKS-LRPS using laser sensor was developed for the measurement of socket roughness and vertical offsets for the first time in Korea. The BKS-LRPS was applied for measuring of socket roughness and also vertical offsets at the specific field sites. Based on this study, BKS-LRPS was successfully applied for measurement of socket roughness and vertical offsets the in the fields, and more appropriate quality control for the vertical offsets have to be needed.
