Abstract:
An excavation is constructed in a limited area because of the high price of land and lack of land. The retaining wall system's primary function is to prevent soil collapse and water drainage to the excavation area. However, the deep excavation needs more stability and careful consideration because the high deformation and settlement occurred due to increasing lateral earth pressure. This paper studies retaining wall systems with no struts (strut-free) for the 20 m deep excavation. The study focuses on the structural behavior of the retaining wall system and the interactions (adhesion) between soil and structural elements. Furthermore, the performance of the RFD system was investigated through finite element analyses using PLAXIS 3D. The maximum wall deflection and surface ground settlement are calculated to measure the retaining wall stability according to its values. Based on the results, the RFD system in elastic behavior had potential, but the demolishing of buttress walls leads to excessive wall deflection and ground settlement.
