MgO계 내화물이 함유된 팽창성 지반에서의 모형말뚝 거동 분석 = Behavior of Model Pile Embedded in Expansive Soil with Magnesia Oxide-Based Refractories

다국어 초록 (Multilingual Abstract)

This study explores the performance of pile foundations in highly expansive soil, incorporating magnesium oxide-based refractory materials. A controlled model chamber, housing a fixed pile, was utilized to induce ground expansion through fused magnesia (FM). The investigation focused on measuring the vertical displacement of FM-sand mixtures and the axial load on the pile in relation to depth and time. The study varied the amount of FM content (FMc) at 30%, 50%, and 70%. The upward movement exhibited an augmentation with increasing FMc, tapering off with depth as accumulation progressed toward the mixture surface. Compression and tensile forces were both evident along the pile for FMc at 30% and 50%, while only a tensile force was observed at an FMc of 70%. These results offer valuable insights for the analysis of pile behavior within FM-sand mixtures.
