【摘要】 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。更多还原

【Abstract】 The Wenchuan earthquake was simulated through the shaking-table test to study slope deformation mechanism and provide an explanation of secondary geo-disasters resulting from the quake.A physical model of large-scale shaking-table was designed,based on previous experimental and research results.The paper introduces the model box,simulation range,similarity relation,rock material,location of monitored sections and sensor layout,as well as the seismic wave loading system.The results of the test indicate that the proposed large-scale shaking-table test design is reasonable.更多还原
