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.

Highlights

In the 1980’s, it was of great importance to the port of Rotterdam, while competing with other major loading ports in countries such as Australia, the United States of America, Canada, South America and South Africa, to be able to facilitate vessels greater than 100 000 dwt
The relationship of the stability of the quay wall is determined by using Blum method, DSheet Piling and Plaxis 3D
- The actual quay wall shows no instability. - In Plaxis 3D, Model 2B will become unstable when exposed to unfavourable conditions

Summary

Introduction

In the 1980’s, it was of great importance to the port of Rotterdam, while competing with other major loading ports in countries such as Australia, the United States of America, Canada, South America and South Africa, to be able to facilitate vessels greater than 100 000 dwt With this in mind, the E.M.O. deep-sea terminal (Fig. 1) was constructed for the throughput of iron and coal which was realized in 1990. During the demolition of the old quay wall much damage are discovered at the tip of the open tubular and intermediate sheet piles. This was an unexpected discovery which according to the recorded events that took place during its service lifetime was not known.
