| 摘 要： | 依据江守一郎相似模型原理建立并验证了回填土边壁(坡)相似模型的相似法则。在此基础上完成了回填土边壁(坡)破坏模式的大比例尺(长 宽 高 = 315 cm 60 cm 250 cm)系列相似模型和自模拟(原型)试验研究,指出此类介质边壁(坡)的变形与破坏具有7大特征,其破坏模式可抽象为平面破坏模式,以往沿用圆弧破坏模式近似进行稳定性分析和支护参数设计不尽合理。 |

| Abstract: | The similarity rule of similar model of filled-soil side wall (slope) by Emori Ichiros similar model theory is established and verified. A series of large-scale (LWH = 315 cm60 cm250 cm) model experiments and self-simulating (prototype) experiments on filled-soil side wall (slope) are carried out. It is shown that the deformation and failure of this medium have seven characteristics,its failure mode can be reduced to plane failure mode,and it is unreasonable to analyze the stability and determine the support parameters with the arc failure mode. |
| Keywords: | soil mechanics filled-soil side wall (slope) similarity rule failure mode testing study |
