Abstract: The axial capacity of a single pile is an important factor in the pile foundation design. But in the complex geological conditions, the soil data often have many categories with a wide variation. There are many inconveniences in the fast determining the axial capacity of a single pile. Due to the complexity and diversity of soil data, it is difficult to save and access. The idea of parametric modeling is therefore adopted. An object model of soil layer is proposed by using Delphi platform. Based on this object model, the software for predicting the single pile axial capacity is developed. The results show that the parameterized object model is simple and convenient. It is also convenient to modify, save and access data. The single pile axial capacity prediction software, developed by using the object model, is simple to operate and computationally efficient.
