| 摘 要： | 边坡开挖后,原有应力平衡遭破坏,若边坡过高、过陡,将产生失稳。当采用预应力地梁锚索对坡面施加一个外力时,由于改善边坡受力状态,可继续维持稳定。但是应力状态的改善程度,每级边坡的合理高度,对此目前尚无较好的方法,本文拟对此进行初步探讨。

| Abstract: | After the digging of a slope, its original stress equilibrium was broken.The slope would lose stability if the slope was high and steep enough. It could be kept stable continuously if an outer force from the prestressing cable-anchor beam acted on the slope, because of the stress state improve-ment. So far, there has been no reasonable methods to determine the degree of the improvement to the stress condition in a slope, and to determine the reasonable height of a single step slope, a first step discussion was presented. |
