Abstract

The present paper analyses the variation of soldier pile and tied background anchored for a case study. The displacement and bending movement have been calculated by limit equilibrium and numerical modelling method. The maximum depth of excavation was 16.3m. The upper strata of this area comprise the alluvium, made up predominantly of sandy silt and silty sand with gravel. Various retaining systems of combination of soldier piles and temporary ground anchors with waler beam and timber lagging have been considered for analysis purpose. Anchor force has been calculated based on limit equilibrium and numerical modeling. Three levels of anchors have been installed with different pretension load. Anchors have been designed with max. load of 600kN with 2 loops of 15.2mm strands with 9m bond length.
