综合了文献[1]和文献[2]中两类群桩基础等代计算模型的优点后,提出了下端固支、上端具有弹簧支承的单柱式模型。它具有十分简单的结构形式,并给出了十分简单的计算公式来计算该模型的4个技术参数。
Combining the advantages of the equivalent models of two groups of pile foundations in references [1] and [2], this paper proposes a single-column model with fixed support at the lower end and spring support at the upper end. It has a very simple structure, and gives a very simple calculation formula to calculate the four technical parameters of the model.
