| 摘 要： | 针对传统刚性挡土结构承受土压力较大的现状,提出刚柔复合挡土结构的概念.利用柔性材料泡沫的易压缩性,增加土与挡土结构接触面的相对位移量,使作用于挡土结构的土压力趋向主动土压力,从而减小挡土结构上的土压力.通过室内模型实验,得到不同厚度泡沫挡墙后的土压力及土体位移,以及泡沫厚度对墙后土压力、土体接触面位移的影响.结果表明:泡沫厚度对土压力与土-结构接触面位移有影响;刚柔复合挡土结构能够明显降低作用于墙体的土压力.

| Abstract: | A rigid-flex composite retaining structure was constructed to reduce the earth pressure against retaining structure by increasing the displacement of soil-structure interface displacement,according to the large earth pressure against traditional rigid retaining structure.The test model of the rigid-flex composite retaining structure and the test process was presented.Model tests were performed for the displacement of the soil and the earth pressure acting against rigid-flex composite retaining structure on ... |
