87 Category 2: Civil Structures 2 Antea Group Contact Evert De Groote Address Roderveldlaan 1 2600 Antwerpen, Belgium Website www.anteagroup.be Antea Group is an international design, engineering and consultancy firm working for governments, organisations and companies. Its operations are in the field of engineering, environment, urban planning, infrastructure and water. The civil engineering department focuses on the strength and stability of buildings and civil construction including quay walls and water related structures. During the design process, every aspect is considered, starting with the geotechnical calculations and ending with the detailed design. “Coeck” Quay - Niel, Belgium SE Owner Waterwegen en Zeekanaal - Afdeling Zeeschelde General Contractor Hye Engineering Office Antea Group Construction Period 11/2013 - 09/2014 On the shore of the Rupel, near the concrete factory of Coeck N.V., a new quay was built. The quay consists of a concrete superstructure on steel piles which is built over a slope. At the back of the slope there is a combined wall. The total length of the quay is 135 m and it consists of 7 sections. In the first 2 sections a loading platform is incorporated which is situated 2.3 m lower than the quay level. The quay was built using prefabricated beams and plates. In total 4 different sections were modelled in SCIA Engineer. The piles, beams and plates were inputted in the program together with the various load cases. The sections were supported in the horizontal plane by inputting non-linear spring supports on the piles. These non-linear supports represent the passive resistance of the soil. The non-linear supports were placed at an interval of 1 to 2 m. Based on the soil characteristics, the group effect of the piles and the effect of the slope, the non-linear supports for each pile row and each depth were different. The modelling of the non-linear spring in combination with the high number of load cases resulted in more than 1,000 non-linear combinations. This made the whole project challenging and required us to test the boundaries of the program and the engineer.
