土与结构相互作用振动台试验模型土设计方法分析
|
摘要
振动台试验是进行土与结构相互作用问题研究的重要手段,对于相互作用体系中地基土的模拟目前仍存在很多讨论。该文首先探讨了模型土相似设计理论与相似设计实施的主要特点,并对近年来国内外常用的模型土设计方法进行了归纳和总结,分析比较了不同设计方法的适用范围与存在的不足,研究结论可以为今后的试验研究提供指导和帮助。
The shaking table test is one of the most important methods for soil-structure interaction research.There still exist some controversies in simulating the foundation soil of an interaction system.In this paper,the basic theory and implement procedure of a similitude design of model soil were analyzed.The designing methods used in recent researches were catalogued and summarized,and the range of application and disadvantages among different methods were analyzed and compared.The results could provide useful and helpful directions for experimental researches in the further.
