摘要
荷载传递函数法是桩荷载传递机理分析的重要方法之一。针对桩土共同作用过程中的桩周土体分别处于弹性与塑性状态的划分,以天然地基抗剪强度随深度线性增长的规律,由荷载传递函数的基本微分方程解得荷载传递的解析表达式,并以实例说明这种分析思路的实用性。
The load transfer function method (LTFM) is a significant means of load transfer mechanism analysis of pile. The paper divides the soil body around pile into two parts, the elastic area and plastic area for the common action of pile soil. According to the law of linear increase of shear sthrength with the depth of natural ground, it gives the solution by the basic differential equation of load transfer function. And the practicability of the method is illustrated by the living example.
