Description
Summary:The roads or buildings constructed on slopes have a high potential for landslides, therefore, it is necessary to have a retaining wall for soil as a form of a preventive strategy. The construction process on slopes usually involves excavation at the bottom and filling at the top. This makes retaining walls designed using a hybrid method the appropriate solution to resolve the problem of landslides. This includes the combination of soil nailing at the bottom and the mechanically-stabilized earth (MSE) wall at the top. This method is new in Indonesia and there is currently no specific design procedure regulating its use. Therefore, a design procedure was proposed and tested based on the existing regulations such as SNI 8460: 2017, FHWA 2015 for soil nailing, and FHWA 2001, 2009 for MSE walls. The process involved using 3 application programs for modeling and analysis which are TensarSoil for MSE walls, SnailPlus for slopes without reinforcement and those with soil nailing, and SLOPE/W for the hybrid wall. This research was also used to design a hybrid wall using this procedure and the product was able to achieve stability
