摘要: 考虑DX桩的实际受力性状,得出了桩基承力扩大盘周边土体的应力应变及位移分析的解析解,基本反映了土体在挤扩过程中的运动规律,并分析了DX桩承力扩大盘(或支)的形成机理。Abstract: An analytical solution for bearing enlarging disk of the DX pile based on its actual bearing characteristic is presented. The result reflects the stress-strain relationship and displacement of the soils near the pile's bearing enlarging disk and basically predicts the moving law of the soils while squeezed. Then the forming mechanism is analyzed.
