Response Analysis of Berthing Structure with Soil–Structure Interaction

2022 
The berthing structures including piles and diaphragm walls are supported on soft marine soils. The soft soils under severe loading are likely to undergo vertical and lateral movement. The anchored diaphragm wall is provided to support the open berth structure against backfill. In this paper, finite element analysis of berthing structure has been carried out using a finite element program ANSYS APDL. The soil strata is modelled as 3D continuum. The response analysis of diaphragm wall for different pretension forces in anchor rod has been carried out. The variation in displacement, shear force and bending moment along the depth of wall is plotted. The result is compared with the case without considering soil–structure interaction. The optimum value of pretension force is obtained as 1050 kN which effectively reduced the deflection of diaphragm wall. The percentage increase in maximum lateral displacement, shear force and bending moment of wall without considering soil–structure interaction effect was found to be 25.265%, 52.523% and 892.944%, respectively.
