摘要
结合千将坪滑坡模型试验,对千将坪滑坡土体相似材料进行了研究.试验以相似三理论为指导得出了相似判据,并采用均匀设计方法确定出材料的配比,最后,采用模糊综合评判法对相似材料的相似性进行了比较,并最终确定出最佳相似材料.试验结果表明,砂、粘土、膨润土所制成的相似材料具有与千将坪滑坡土体相似的物理性质,用来在模型试验中模拟滑坡土体是合适的.
Based on the physical model experiment of Qianjiangping landslide, the similar material model tests are conducted. Firstly, based on the theories of similarity the similarity criterion is established. And then the uniform design is used to ascertain the mixture ration of the similar material. At last, the optimum similar material is obtained by the fuzzy mathematics theory. The experimental results show that the similar material which was mixed by sand, clay and bentonite has the similar physical characters with the soil of Qianjiangping landslide. So, this similar material can be used for the physical model experiment of landslide.
