Abstract
The main inducement for collapse disaster of gentle incline rock slope is differential weathering, and for rock breakage of it is rock cell. On the study of gentle incline rock slope in this paper, we established the mechanics mode of arbitrary rock in gentle incline rock slope, analyzed the failure mechanism of gentle incline rock slope during the process of rock cell retreat, and established the distinguish method of its stability based on fracture mechanics. Then, taking the rock mass slope of JIMINGSHAN in CHENGKOU as an example, analyzed the stability change law of each rock block during the process of rock cell retreated. The study result of this essay can provide certain theoretical foundation for the prevention of disaster of gentle incline rock slope.
