Wrap-around reinforced structure gradually became proposed hilly road repair method due to its flexible structure and rapid construction. Moreover, in-situ soil was successfully used as backfill material in Taiwan due to the lack of natural aggregate, which further reduced construction cost. Under well-controlled compaction quality of in-situ soil and thoughtful arrangement of drainage system circumstances, here complex reinforced structure combined with drilling piles and soil anchors was built. Through one year of inclinometer monitor and water level wells observation, increment of displacement of overall slope was decreased with ground depth and almost none displacement is detected under 10m depth.
