Abstract: The mechanism of the grouted micropile is introduced in this paper based on a case history of the filling slope failure mitigation for a steel mill site. The design approach and the construction procedures are also discussed. Throughout the monitoring during the construction and the operation, it is proved that the micropile method is a reliable slope stability mitigation method.

Key words: slope failure mitigation, grouted micrppiles, shear strength, slope stability
