In special situations, the treatment plan for embankment failure is hindered by cracking and sliding failure in highway embankment slopes. For example, the prestressed anchor cable or bolt frame beam is not suitable as the absence of a hard anchorage ground layer, or slip deformation embankment cannot be removed and rebuilt to protect the existing sub-grade. An ideal solution in this situation is to use grid-work girders of oblique steel pipe piles. The grouting of oblique steel pipe piles is a method that uses a composite foundation of steel pipe piles to reinforce slopes. Specifically, grout is embedded into steel pipe piles and passes through the sliding surface. Grouting can change deformable soil into composite soil and protect steel pipes from corrosion. Steel pipe piles serve as reinforcement by applying anti-slide force directly onto the soil. By means of a successful example of slope deformation treatment, this work discusses the scope of the application, the stress characteristics, the changes in slope stability, and the reinforcement effects after slope strengthening. The results would benefit engineering projects involving similar slope failure treatments.
