Dimensionamento de cortina atirantada.

Abstract

The soil containment structures represent the advancement of engineering amidst urbanization in the country. The anchored curtain has proven performance in the area of slope stabilization , particularly in overcoming significant heights and high loads. This study addresses the structural design of an anchored curtain, employing current standards for reinforced concrete, anchored tie rods, slope stability, and the geotechnical design method developed by Costa Nunes. The calculations were carried out using an Excel spreadsheet and stability verification through the software developed by FINE Engineering, specifically the GEO5, for solving geotechnical problems. Initially, a literature review is conducted on the types of curtains used, stability verification met hods, and geotechnical and structural calculation methods. Based on the stabilization forces obtained through the Brazilian anchoring method, an appropriate single bar tie rod was selected. The acting load on the wall was calculated, and internal forces fo r structural design were obtained using the Ftool software. It became evident that the structural design needs to be accurately calculated to meet the criteria for tie rod prestressing and loading requirements.
