چکیده مقاله
Steel sheet piles driven in harsh marine environments are sometimes so corroded that cannot be repaired effectively through coating them with retrofitting materials since due to high corrosion rates –commonly happens in splash/tidal zones– the connection between the tie rod and sheet pile is gradually removed It endangers structural safety and causes big displacements in the whole soil structure system These displacements in turn cause failure in the soil behind sheet pile wall In this condition –in which the sheet pile has lost one of its supports and its stiffness had been significantly reduced– application of convenient retrofitting methods for rehabilitation of structural sheet pile performance is not considered to be a suitable procedure In this research, PLAXIS is used as modeling software The primary models are created with a row of existing corroded sheet piles, anchored with tie rods of different reduced cross sections in the location of connection due to corroding ambient It gives the critical amount of corrosion in tie rod cross section The next model is created with the previous existing sheet piles, tie rods of critical reduced cross section and a row of new auxiliary sheet piles –having two thirds of cross sectional strength properties of the existing sheet piles The aim of this paper is to investigate if new sheet piling could limit displacements and stresses in existing soil structure system
