Abstract

Abstract: To cut a bedding high rock slope, usually it is necessary to take some reinforced structures in advance. How to determine the range of disturbed zone properly is a core problem. According to the stress condition and displacement condition after cutting a slope, the disturbed zone can be defined. Taking the bedding high rock slopes of Wanzhou-Liangping Expressway for example, mechanical properties and influential factors of disturbed zone are introduced. In addition, the disturbed zone of bedding high rock slope is studied on the basis of rock mass structure. It is most unstable when the inclination of rock stratum is between 15－30°; also there is a relation between length of disturbed zone and depth of cutting. The results show that the ratio of length of disturbed zone to depth of cutting is situated in between 2 and 5 to most sandstone and mudstone bedding high rock slopes.

Key words: bedding high rock slope, depth of cutting, length of disturbed zone, influential factors, inclination of rock stratum
