基于Matlab GUI平台的桥梁桩基承载力计算系统

Bearing Capacity Calculation System of Bridge Pile Foundation Based on Matlab GUI Platform

桥梁桩基承载力计算在整个下部结构计算过程中占有非常重要的地位,结合《公路桥涵地基与基础设计规范》(JTGD63-2007)对摩擦桩计算的规定,利用Matlab强大的数学分析功能进行求解,并利用Matlab的GU(IGraphical User Interface)编制了相应的计算程序,在程序中输入相应钻孔的地质信息、桩基设计尺寸和不同工况下的荷载信息,程序就能得到计算结果;通过一个工程实例计算表明,利用本程序计算得到的桩端承载力结果,满足经济、安全的需要,具有很强的工程应用价值。

The bearing capacity calculation of bridge pile foundation plays a very important role in the whole process of substructure calculation.Combined with the stipulations of the friction pile calculation in Standard for Design of Subgrade and Foundation of Highway Bridge Culverts(JTG D63-2007),the article uses the powerful mathematical analysis function of Matlab to carry out the solving,and applies the Graphical User Interface(GUI) of Matlab to compile the corresponding computer program.The program can achieve the computation result by inputting the relevant geological information of drilling,the design dimensions of pile foundation,and the loading information under the different constructing conditions into the program.The calculation result of an engineering case shows that the bearing capacity achieved by this program calculation can satisfy the demands of economy and security,which has the powerful engineering application value.
