天然地基和桩基承载力计算的程序实现

确定天然地基和桩基承载力是交通土建工程中的一项重要内容,而实际工程设计计算使用规范方法、通过手算并辅之以简单电算来实现。文章在简述天然地基和桩基承载力规范确定方法的基础上,说明了使用可视化程序设计平台Visual C++进行编制相应应用程序的过程。在建立程序框架基础上,通过菜单、对话框及相应控件的外观可视化设计,改进了地基土各种计算参数的确定方法,编制了相应的消息处理函数,同时制作了应用程序的帮助文件与程序安装版。使用所编可视化程序,不再需要查表,数据输入输出及承载力计算过程均通过可视化界面操作,计算过程简单、实用。文章的两个算例表明,计算结果与实际计算结果非常一致,这说明该方法具有一定的应用和推广价值。

The visually programming to compute bearing capacity of subsoils and pile foundations

The determination of the bearing capacity for natural sub-soils and pile foundations is a fundamen- tal aspect in transportation engineering and civil engineering. The code method and simple computer calcu- lation are used for the determination in practical design. In this paper, after presented the code methods for the determination of the capacities, an application program was implemented using visual programming platform VC++: the program frame was first established; the menus, dialogs and related controls were then visually designed; some message functions were also coded using the improvement in inputting different computational parameters; the help documents were further coded out; and installation version of the program were finally setup. In this program, finding parameters from the tables will be discarded away. Data input/output and computation process of bearing capacity are all completed both simply and practically by a visual media. It shows that there is a good agreement between the capacity values in this paper and those in ordinary method from two examples.
