【摘要】 本文针对大面积地面堆载条件下的邻近单桩以及厂房内大面积地面堆载作用下的整个结构进行分析，假定桩为简单的弹性地基梁，桩周土采用离散的弹簧单元，柱子采用梁单元，桁架采用杆单元。基于体系的变形协调及受力平衡，编制了相应的有限元计算程序。通过算例分析，对影响体系变形的各种复杂因素进行了系统的比较分析，讨论了地基堆载、桩身刚度、堆载范围，桩顶约束、表层土体刚度对桩及上部结构的变形和内力的影响。更多还原

【Abstract】 This article analyzes the pile-soil interaction adjacent to superficial surcharge and the interaction of the surcharge-passive pile-superstructure. The pile and column are modeled plane beam element, soil to be spring element, truss is to be bar element. Based on the compatibility condition of displacement and force, the corresponding programme has been encoded by author. Through two examples analysis, then it analyzed some factors to deformation and inter force of pile, column and truss, such as the grade of surcharge, the rigidity of pile, the distance between surcharge and pile, the constraint condition of pile peak and the rigidity of surface soil.更多还原
