摘　　要：针对目前地质构造模型试验装置的不足,在研究国内外已有模型试验装置优缺点的基础上,通过试验模型相似准则的选取和相似比的确立,研制出了一种结构简单、组装灵活、使用方便、适合不同尺寸逆断层物理模型的试验装置。该试验装置由模型箱、加载系统及反力装置、数据量测系统三大部分组成,采用电液伺服加载系统,使用数采系统进行实时数据测量。使用结果表明,研制的试验装置系统稳定、性能可靠,不仅直观再现了逆断层的演化过程,而且实现了地质构造应力和变形量的实时测量,为地质过程的定量化研究和地应力的测量提供了一种新的模型试验方法和研究手段。Directing at the flaws of geological structure model test device, on the basis of studying the ad- vantages and disadvantages of model test device at home and abroad, according to select appropriate sim- ilarity criterion and establish similarity ratio, physical model test device showing evolution process of the reverse fault is developed. This device is simple and easy to use with flexible assembly; therefore it can simulate geological formations with different sizes. This device has three major components： model box, loading system and counterforce device, data measurement system. And using electro-hydraulic servo loading system, this test device uses the data acquisition system for real-time data measurement. The test results show that the developed test device system is stable and reliable. It not only reproduce the evolu- tion process of reverse fault, but also realize real-time measurements of the geological evolution of the tectonic stress and deformation, which provides a new model test method and a research tool for the quantitative study of the geological processes and tectonic stress measurement.
