基于Delphi软件的土层参数化建模与开发

Soil Parameters Object Modeling and Development Using Delphi

桩基承载力是桩基础设计的重要内容,但在复杂地质条件时,土层参数数据往往类目繁多、数据量大,快速确定桩基承载力存在着诸多不便。针对土层参数数据复杂多样不便存取的问题,采用参数化建模的思想,基于Delphi开发平台,开发了土层参数、集中力、圆截面、修正后桩端土承载力、单行文本和对象选择器等6个对象模型,并据此研发了桩基单桩轴向受压承载力快速计算模式,实现了从对象建模到专业计算的软件开发模式。建好的对象模型具有通用性,可应用于构造不同的计算模式,从而实现不同的专业计算功能。结果表明:该参数化对象模型建模简单,交互式修改和存取方便,利用该对象模型开发的桩基计算软件,操作简单、计算高效;该建模方法可为工程行业软件的开发提供参考。

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.
