Abstract: This paper presents a literature review of the development of the tiered wall with anchor pile system for the deep excavation support. Various earth pressure estimation methods for this system are reviewed in the paper. Different design analysis results from the assumptions of rigid supporting structures and structures with deformed anchor piles, walers and supporting components are also presented.

Key words: Tiered Wall with Anchor Piles, Equivalent Beam Method, Elastic Beam Method, Deformation Compatibility Method, Soil Retaining Theory, Technological Developments
