In view of the existing flaws of the grounding calculation software and the insufficiency, proposed and designed a kind of based on the Qt libraries grounding calculation analysis software. Input data, in order to facilitate a variety of visual way to check the data as the goal, with each module are independent of each other, view, data from each other as the design thinking, software were divided into three modules: data input module, the simulation calculation and calculation results show that the output module, module between file as data transmission and storage media, make the software has a good stability. Then, several key problems of software has carried on the brief description, and the comparison between the numerical example against doing validation, proved the validity of the software.
