Abstract

One of work methods in increasing the double track lane in Java island is application of geosynthetic MSE-wall to retain new railway bed beside the existing rail track. When geosynthetic applied as a temporary reinforcement, it would be ineffective due to some considerations such as the economic aspect, because the geosynthetic function as MSE-wall will disappear if the elevation of the existing railway is increased as high as the new railway. Bamboo mats can principally be applied to replace geosytethic as temporary MSE-wall. Its more cheaper and biologically degradable feature is beneficial when used as a temporary MSE-wall. To design the structure of MSE-wall, the pullout resistance value shall be obtained by a test. This research aims to inform that bamboo mats as an organic local craft are feasible to be used as a slope temporary reinforcement material. The pullout resistance test refers to SNI 8128:2016. The pullout resistance test shows that Ci value of the bamboo mat in the heap of railway bed is 0.417. As the sample of numeric simulation, this temporary bamboo mat MSE-wall is analyzed using Geo5 software. The numeric simulation on bamboo mat MSE-wall with 2.2 m high slope and the load of railway bed construction plus the train shows that they are safe from both internal and external collapses. The lowest safety factor is 1.53 with the potential of collapse due to the global slope stability. When applied as slope reinforcement, the plait size available in the market should be considered.
