摘要
Abstract
In high geo-stress area, many deep tension fractures developed in the inside of some high and steep slope with horizontal depth of 200 to 300 m or even deeper, which is beyond the understanding of unloading laws in practical experience. So a reasonable explanation of this special engineering and geological phenomenon becomes a new subject. The genetic mechanism of tension fracture in deep unloading condition is further discussed on the basis of the analysis and summary of previous research re-sults, in terms of around environment, rock structure and geological tectonics. The results in current stage showed that the ten-sion fracture in deep unloading condition can partially affect the slope stability;the fracture would develop and expand under in-ner force or water filling condition, so as to control the stability of the slope.关键词
