The Research And Application Of Anchorage Technical For Rock Slope

Slope is a common geological environment in our human activities, it's also a common engineering style. We should pay much attention to the slope engineering, because the failure of slope can cause catastrophic results, and limit our society's development. So study the stability of slope and anchoring technique is very important.This paper carefully analysis the structure of rock slope, its structure of rock mass and mechanical properties, point out that the important meaning of the analysis of rock slop failure. It also point out the rule when analysis the rock slope, that is, structural control of rock mass and consider the failure style of loosening structure. This paper analysis the stress before and after it formed, point out that the stress status is always change with the time, and the range of the change, also with the permissive strength are very important, they can determine the slope's failure or not. The paper analysis the causes affecting the distribute of the stress of the rock slope, generalize the mechanical model of rock slope, and point out the reinforce principle of rock bolt, give the formulation of reinforce principle. It generalize the affect factors of the anchor reinforcement, point out the right time, rock mass style and climate are the main reason. This paper also introduces the stability analysis methods, the use of the FOS, and the calculating method of anchoring force.Applied to a case with anchoring reinforce rock slope, we can fined that the theory is well agreed with the in situ results.
