Stability Analysis Quay Wall at The Amazonehaven, Port of Rotterdam

Abstract

Abstract. The stability of any structure is an important aspect in civil engineering. This aspect is the subject of the researched quay wall at the Amazonehaven, port of Rotterdam. The quay wall with a relieving platform structure had in various section, over the entire 900m length of the quay, large deformations at the toe of the combined wall. The purpose was to analyse and quantify the influence of the deformed combined wall on the stability of the quay wall, its service lifetime. To obtain a better insight into the concept of stability, analytical methods based on the Blum theory, beam on elastic foundation method and finite element method using Plaxis 3D were applied and compared. The finite element method, Plaxis 3D, proved to be a better method to investigate the quay wall. Plaxis 3D takes into account the 3-dimensional effects of the quay wall and considers the actual soil behaviour during calculation which is a sophisticated manner of modelling a quay wall. A calibration model (which is the actual designed quay wall) and a series of models with various penetration depth of the combined wall are modelled. Also, a safety analysis of the soil parameters were applied to the various models.

Furthermore, the field bending moment increases as the surface load increases which leads to a freely imposed bending moment.…”

“…The general problem of security of marine transportation systems and reliability of their operation is analyzed in [8]. An analysis of stress-strained state of a berth with the use of the finite element method, but without taking into consideration the random character of the influence of operational loads on a berth, was performed in [9].…”
