PRACTICAL EARTH ANCHORING TECHNOLOGY FOR STRENGTHENING SLOPE WALL PROTECTION (CASE STUDY: DG. SIRUA ROAD POST CONSTRUCTION FAILURE WITH SKYHOOK ??? GRID BEAM TECHNOLOGY IN MAKASSAR CITY ??? INDONESIA)

摘要

The application of soil anchoring system and grid beam method of strengthening protection wall post construction failure was observed in this research. The construction of the slope wall protection is situated to suit the existence of barrier made for aqueduct. Based on the numerical simulation on scenario of potential causes of slope failure, it indicates several phenomena such as the stability of barrier foundation experiences drastic drop. Scrutinizing the result of investigation and ideal design criterion for structural element of barriers, the condition function of existing protection wall has the factor of slope stability SF=1.01~1.09, which is categorized as not safe and condition barrier failure. The strengthening method of soil anchoring (Skyhook Earth Anchor, with the capacity of 4 tons) which is combined with grid beam manages to improve the barrier???s stability to SF=1.24~1.46 post construction and reduce horizontal displacement of barrier.
