Tutorial 21. Design and Analysis of Steel Sheet Pile Wall for Temporary Excavation: Geo5 & PLAXIS 2D

𝐌𝐚𝐬𝐭𝐞𝐫𝐢𝐧𝐠 𝐑𝐞𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐖𝐚𝐥𝐥𝐬 𝐚𝐧𝐝 𝐒𝐡𝐨𝐫𝐢𝐧𝐠 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 𝐔𝐬𝐢𝐧𝐠 𝐏𝐋𝐀𝐗𝐈𝐒 𝟐𝐃 In this tutorial, the design and analysis of a steel sheet pile retaining wall for a temporary excavation are explained. The following aspects are covered to provide a comprehensive understanding: ✔ Calculation of Embedded Length of Sheet Pile Using GEO5 – The required embedment depth is determined to ensure structural stability. ✔ Verification of Sheet Pile Cross Section Using GEO5 – The adequacy of the selected sheet pile section is checked against design requirements. ✔ Stability Analysis Using GEO5 – The overall stability of the retaining system is assessed under different loading conditions. ✔ Deformation Analysis in PLAXIS 2D – The expected deformations and lateral displacements of the sheet pile wall are examined. ✔ Safety Analysis Using PLAXIS 2D – The factor of safety against failure is evaluated to ensure design reliability. A comparison between the results obtained from GEO5 and PLAXIS 2D is presented, highlighting differences in calculation approaches and interpretation. Additionally, solutions are provided to improve stability when excessive deformation or failure is predicted.
