Tóm tắt

This research introduces a novel method for optimising the design of precast reinforced concrete (SW) sheet piles that are used in coastal retaining walls. The study examined key parameters, including backfill embankment height, surcharge loads, and SW sheet pile geometry to evaluate the stability and performance of a retaining wall. Using the Python-Plaxis interface, a set of numerical models were developed automating the analysis and significantly reducing computational time. In total about 70 models were conducted; their results were used to establish a Gene Expression Programming (GEP) model between input and output parameters. The research results confirm that combining FEM and GEP is a valid approach for design optimisation of complex geotechnical structures. A parametric study indicated that the height of backfill embankment and the length of SW piles are critical variables. This integrated approach provides engineers an efficient tool in the design of soft soil in coastal regions.
