S Slope reinforcement is a structure to hold the soil on a slope with a certain height and slope. Many methods of reinforcement can be used in designing reinforcement for slopes, but the ones commonly used are soil nailing and ground anchors. In general, only one reinforcement method is used per slope, soil nailing or ground anchor only. Project X, which is a temporary residential area project on the Bali Island, combines soil nailing reinforcement with a ground anchor on one slope reinforcement. Meanwhile, the combination method of reinforcement has no regulations. Evaluation of the slope reinforcement combination is carried out using SNI and FHWA to determine the suitability of project data with applicable regulations. Evaluation is carried out by comparing project data from each method, that is data on soil nailing projects evaluated with the provisions of soil nailing and data for ground anchor projects evaluated with terms and provisions of ground anchor. From the evaluation results, there are some data that are not in accordance with the provisions, which means that the use of a combination of slopereinforcement in Project X has deviated from the applicable provisions. With this deviation, the authors carried out three new reinforcement models for Project X, which are soil nailing, ground anchor and a combination of soil nailing and ground anchor which is in accordance with SNI 8460: 2017 or FHWA with the Bishop method in the Geostudio 2018 program. The three new reinforcement modeling can be used as analternative for slope reinforcement in Project X because it has met the safety factor in accordance with SNI 8460 : 2017 which is 1.5, which means that a new slope is obtained that is safe and in accordance with applicable regulations.
