Development of Numerical Software for Sheet Pile Wall

Development of numerical Software for Sheet Pile Wall This report presents the methodology and validation of the software program developed to analyze the sheet pile walls using the Soil Structure Interaction method. The report presents the general theory behind the SSI method, and how it can be used to analyze the behavior of sheet pile walls and the anchors. The software is based on some assumptions that it can only consider a single layer of soil with constant section throughout its depth. MATLAB coding was used to develop a program that solves multiple equations developed from SSI method to generate the moment, shear, deflection, and slope diagrams for the sheet pile walls. The results obtained from the software were compared with the existing spreadsheet for the analysis of sheet pile walls using SSI method. The results obtained were identical as that of the spreadsheet. The results were also compared with other software programs developed to analyze sheet pile walls based on other methods. The SPW software based on beam theory was used to compare the results. The difference in the extreme values of moment and shear in the case of sheet piles without anchors was less than 2% which is negligible. However, the difference in case of sheet pile wall with anchors generated slightly different values. The difference was 16.25% in case of minimum shear. This difference can be because of the different approaches used by both the methods to analyze the anchors in the sheet pile walls. The future recommendations include the inculcation of multiple soil layers and varying section of the sheet pile wall in the analysis procedure.
