| 摘 要： | 推导了边坡坡体及锚固体的离心相似模型,得出了相关参数的相似比尺。通过试验得出了花岗岩风化残积土边坡可能以平面形式失稳也可能产生圆弧滑动,分析了含水量对破坏形式的影响。通过试验得出无控制性结构面的边坡的极限稳定高度与坡角的关系大致满足马斯洛夫方程。

| Abstract: | This paper presents centrifugal analogous model of the sub-soil slope and associated matching scales of some parameters. The test results from the centrifugal model experiments show that the granite residual soil slope will probably fail in two modes: plane failure and arc sliding. The effects of water content are also analyzed. The relationship of gradient and corresponding critical slope height of the slope without significant constructional surface fits Masilofo equation. |
