Abstract

In this study, a series of scaled model test were carried out in order to find factors that influence the ultimate load of underreamed anchors. Model anchors were made of arcril and 3cm in diameter. Series of tests were performed with various conditions such as density of soil, diameter of bulb, and number of bulb. Type of soil was Jumunjin sand and relative density varied 40%, 60%, 80%.
