从侧向受荷桩的受力和变形机理出发 ,提出了地面超载下邻桩侧向变形的计算分析方法。该方法考虑了桩身侧向受力随桩身侧向变形的关系 ,并据此推导了关于邻桩受力和变形的微分方程和有限元计算方法 ,编制了计算程序。最后 ,利用实测数据验证了该方法的合理性和实用性 ,这将为受地面堆载影响的厂房和仓库的桩基设计与加固提供依据 Based on the stress and deformation mechanism of laterally loaded piles, a calculation and analysis method of lateral deformation of adjacent piles under ground overload is proposed. The method takes into account the relationship between the lateral stress of pile body and the lateral deformation of pile body, and deduces the differential equation and the finite element method about the stress and deformation of the adjacent pile based on this method. Finally, the measured data are used to verify the rationality and practicability of this method, which will provide the basis for the design and reinforcement of the pile foundation of the plant and warehouse affected by ground heaps
