【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。更多还原

【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.更多还原
