为了深入研究斜坡变形破坏机理,为汶川地震诱发次生地质灾害提供理论解释,通过振动台试验模拟汶川地震过程。在参考已有实验和研究成果的基础上,对大型振动台物理模型进行设计,介绍模型箱、模拟范围、模型相似关系、模型岩层材料、各监测断面的位置和传感器的布置,编制地震波加载制度。结果表明,拟定的大型振动台模型试验设计方案是合理的。
In order to deeply study the mechanism of slope deformation and failure, provide a theoretical explanation for the secondary geological disasters induced by the Wenchuan earthquake and simulate the Wenchuan earthquake process by shaking table test. Based on the existing experimental and research results, the physical model of a large shaker is designed. The model box, the simulation range, the similarity of the model, the rock material of the model, the position of each monitoring section and the sensor layout are introduced. The seismic loading system . The results show that the proposed large-scale shaking table model test design is reasonable.
