Purpose The design of cantilever pile walls (CPWs) presents several common challenges. These challenges include soil variability, groundwater conditions, complex loading construction considerations, structural integrity, uncertainties in parameters and monitoring costs. Accordingly, this paper is to provide a detailed literature review on the criteria CPWs, specifically cohesionless soil. This study aims present comprehensive overview current state knowledge area. Design/methodology/approach uses approach gather information CPWs It covers various aspects such as excavation support systems (ESSs), deformation behavior, criteria, lateral earth pressure calculation theories, load distribution methods conventional approaches. Findings identifies discusses associated with highlights determining potential for excessive wall deformations. approaches methodologies proposed by researchers address these Originality/value contributes field geotechnical engineering providing valuable resource engineers involved analysis offers insights into solutions specific soil, filling gap existing base. draws attention limitations analytical that neglect serviceability limit assume rigid plastic highlighting need improved context.

In the present study used numerical analysis to investigate lateral displacement of secant pile walls and ground surface settlement problems for a case study. Three structural systems were modelled, analyzed, designed determine best solution each case: cantilever, anchored, strutted wall (SPW). Field data from examine settlements wall. Plaxis finite-element software was create plane-strain model. The findings numerous simulations performed are compared field data, which shows very strong coherence.
