This paper addresses key considerations for the design of a ca. 500 m long exposed container quay serving as part of a port expansion in the Port of Ashdod, Israel. The quay was designed to accommodate Panamax type vessels and was intended to be partially constructed early in the project to provide protection from waves in the main construction area. The quay is being constructed adjacent to the existing operational port, and therefore the type of structure and sequence of construction had to consider its potential effects on downtime in the existing port due to wave reflection.
In developing the concept design, numerical wave modeling was carried out to assess the wave climate both in the construction area and at the existing (operating) port, considering the different stages of construction. The selected quay structure consists of a steel pipe pile supported concrete platform, with a combination stone and Antifer cube revetment below the platform for wave absorption.
To verify estimated wave forces and potential damage to the revetment during both construction and once the port goes into operation, and to design the quay structural elements for wave loading during both the construction and operational stages, two-dimensional physical model testing was carried out in a laboratory wave flume. Tests were performed using irregular waves, and pressure gauges were installed to measure the wave induced pressures on the model deck slab, pile caps, optional fascia beam and approach slab.
This paper focuses on the wave conditions at critical locations within the construction area during the various stages of construction, including downtime assessment for the existing port, and wave pressures on the new quay structure. It also compares wave pressure results between semi-empirical relationships and the physical modeling.
