| Abstract |
BDH PLT (this is, Bi-directional High pressure Pile Load Test) is a pile load test using high pressure double-acting oil jack and can be applied to overcome the problems of loading capacity and construction field conditions.In this study, to confirm the bearing capacity and the settlement of large-diameter drilled shafts of high-rise building, the BDH PLT was suggested. Also, BDH PLT was applied to 2 large-diameter drilled shafts of high-rise building. Bases on the analysis of the results, quality assurance, confirmation of the base resistance and frictional resistance and reduction effect of foundation construction cost were analysed. |
