| 摘 要： | 大型振动台模型试验是边坡动力响应和破坏模式研究的重要手段，其中相似材料的选择是决定试验能否成功的关键。以黄土地区2类典型边坡为研究对象，在对滑坡体原状土样开展室内土动力学测试的基础上，提出6种相似比条件下振动台模型试验相似材料的配比方法；对2种相似比条件下相似材料的参数进行量纲分析，依据相似判据、相似准则的约束，以模糊数学理论进行优化，并提出大型土质边坡振动台试验的材料相似性评价体系。

| Abstract: | The large-scale shaking table model test is an important means to study the dynamic response and failure mode of slopes; selection of similar materials is the key to the success of the test. Two types of representative slopes in the loess region were taken as research objects, based on laboratory soil dynamics tests conducted on undisturbed soils of loess landslides. Different mixture ratio methods of similar materials with six different similar ratios are proposed. Parameters of similar materials under the condition of two similar ratios were analyzed by quantitative outline. According to the constraint of similar criteria, an evaluation system for material similarity of soil slopes in large-scale shaking table tests is proposed and then optimized by fuzzy mathematical theory. |
