초록
Ultimate lateral loaded pile capacity is influenced by soil conditions. Methods of calculating ultimate lateral loaded pile capacity in homogeneous soil were suggested by a lot of previous researchers.(Broms 1964, Petrasovits & Award 1972, Prasad & Chari 1999, Zhang et al. 2005) There is only few homogeneous soil in actual condition, however, it could be not conviction that the methods from previous researchers are correct in multi-layered soil. In this study, the variation of ultimate lateral loaded pile capacity was analyzed in the various multi-layered conditions, ultimate lateral loaded pile capacity was calculated by the methods from previous researchers. For this study, the Lateral Pile Load Tests (LPLT) were performed in calibration chamber, the soil was composed by 3 layers and each layers had a various relative density. The results of LPLT were compared with calculated results from the previous researchers.
