| 摘 要： | 某拟建水电站坝前左岸反倾边坡,除正常卸荷裂隙外,在坡体深处发育一系列变形破裂迹象.对其成因分析研究表明,这套深部破裂是处于高地应力环境的反倾边坡,在河谷快速下切过程中,发生深部卸荷松弛所致,属于一种稳定的变形破裂结构.这一认识有助于正确评价坝前左岸边坡稳定性.

| Abstract: | The geologic exploration shows that except the normal relaxed cracks,there exists a kind of deep-seated deformation-fracture system inside the left bank slope in the front of a dam.The genesis of the fracture system is studied in this paper.It can be concluded that the fracture system observed in the high slope,being reverse and in a high-intensive geo-stress environment,is caused by the stress release during the rapid down-cutting of the river.Therefore,this fracture system is a stable structure.This conclusion will be conducive to the evaluation of the high slope stability. |
