地质构造物理模拟实验模型的相似分析

把地质构造物理模拟实验模型抽象为动力相似问题进行讨论，用相似理论分析导出了地质构造物理模型的相似准则并给出了相似比，认为几何相似、动力相似、材料相似和边界相似是反映地质构造现象的主要相似条件。时间相似、运动相似和其他相似条件是反映地质构造现象的次要相似条件。地质构造物理模拟实验能够直观定性的解释基本的地质构造现象，有针对性地模拟特定的地质构造现象并给以定性分析解释。由于地质构造尺度的宏大，经历的久远和形变的复杂性，地质构造物理模型设计时几乎不可能完全满足相似原理的适用条件，因此，各种地质构造物理模拟实验还不十分令人满意。

Similar analysis of geological structure physical model

Using the means of similar analysis, this paper derives such similar standard and ratio as geometric similar, time similar, dynamic similar, movement similar, and material similar with geological structure physical model, discusses the experimental model, means, materials and the boundary condition of geological structure physical modeling geological structure patterns with differe thinks that the geometric similar, dyna similar condition reflecting essential pr experiment, points out that they might simulate various complex nt materials under the definitive boundary condition. The author mic similar, material similar and boundary similar are primary operties of the geological structure, but the time similar and movement similar are secondary similar condition reflecting its appearance properties. It is difficult to demand the geological structure patterns physical model to whole satisfy the similar condition, because geometric dimension of geological structure is immense, its elapsed time is too long and its structure deformation is considerably complex; therefore, the people are not satisfied with the results of geological structure physical modeling experiment yet.
