相似材料是地质力学模型试验成功的关健。在参考前人研究成果的基础上，根据相似材料配比遵循的原则，通过大量的试验，研制出了材料重度可调范围大，抗压强度和弹性模量低，性能稳定不受温度和湿度的影响，且无毒害、价格便宜、制作工艺简单，能够较为精确地模拟锦屏工程实际岩体的模型材料，其研制方法正确，试验结果可靠。

Similarity of material is a key factor for geomecha nical model experiment. In this paper a lot of tests were made according to similar criteria and the study results of other experts. The model material can accurately simulate rock features at the site of Jingping Project， which can be suitable for a wide range of gravity density, possesses low compression strength, and elastic modulus, remains steady property in different temperatures and moistures, has no pollution on environment, is cheap in cost and is simple in manufacturing technique. Experiments verify that studying method is correct and the result is reliable.
