In the process of development of the national land, a number of cut-slopes are made. In some cases, rock slopes may have some stability problems. Typically, the stability of rock slopes are related to orientation of discontinuous planes and degree of weathering of rocks, etc. In order to effectively stabilize the rock slope where some stability problems take place, we need to exercise sound engineering judgement.
In this thesis, a case study on reinforcement for a failed rock slope is introduced. An extensive field investigations and analyses were performed and the most effective way of stabilizing the slope was suggested.
Based on the analyses, slope stability, constructability, and economical efficiency, for both dry season and rainy season are satisfactory, when the soil nailing is applied to the upper part of the slope.
This study can be a good example for a similar situation where a rock slope failure occurs.
