Abstract: Geotechnical centrifuge model test can reproduce the deformation process in self-gravity stress field,intuitively reveal the mechanism of deformation and damages,and can provide other analytical methods with true and reliable parameters,thus it has been more and more widely used.However,after filling the test model according to the scale similarity,the calculation of the center of gravity of geotechnical centrifuge test model is simple but is also a time-consuming process.Associated with relative physical and mechanical knowledge,the formula of the center of gravity of the experimental model is deduced and then simplified.Furthermore,the basic idea of using VB programming language to simplify the calculation process is proposed,which can provide forceful support for rapid and accurate completion of the experiment.

Key words: geotechnical centrifuge model test, the center of gravity, mathematical model, Visual Basic programming language
