摘　　要：土工离心模型试验能再现自重应力场以及与自重有关的变形过程,直观揭示变形破坏的机理,并能为其它分析方法提供真实可靠的参数依据,而得到越来越广泛的应用。然而按相似比尺关系填筑试验模型后,计算模型的重心这一工序简单却繁杂,费工费时。结合相关物理力学知识,对试验模型重心计算公式进行推导和简化,并提出应用VB语言简化计算过程的基本思路,将会为快速准确地完成试验过程提供有力支持。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 proeess. 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.
