摘要
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 。
A method of calculating lateral displacement of adjacent pile caused by overcharge on ground is put forward by considering relationship between pressure on the pile and its deformation.Based on its differential equation and FEM,the method is programmed and examined by results of field measurement.So it is sound and can provide important reference to design and improve pile foundation affected by overcharge.
