A little way off the coastline of Dubai lie four remarkable islands in the shape of gigantic palm trees: Palm Jumeirah, Palm Jebel Ali, and Palm Deira, still under development. Each consists of peninsulas stretching from a trunk abutting to the Dubai coastline, and capped further outward by a great seawall for protection. It must have needed very many geotechnical consultants to make the needed analyses of the site’s seabed, each geotechnical consultant an expert in seabed engineering. Because creating an island out of shifting undersea sand will require a lot of engineering expertise even before anything can be put down on paper, prior to making any physical construction.
The Palm Jumeirah Crescent or jetty is just 13 feet higher than the sea height at ebb tide, and rises from 34 feet of water at its deepest point. Its engineers state that it is elevated enough not to sink in the rise of the sea level when global warming really occur, or any tsunamis that might develop in the Persian Gulf. The jetty is formed from rocks taken from the mountains. At its bottom is sand covered by a geo-textile or woven mesh to inhibit the sand from flowing out. Weighing down this ‘wrapped’ sand is a stratum of one-ton rocks, over it two strata of six-ton stones sit to be the top part.
The isthmuses jutting from the central avenue are created also from sand taken from the seabottom and then vibro-compacted to bear structures. Palm Jumeirah was created from 3,257,212,970.389 cubic feet of sand. Vibro-compacting is done by saturating the sand with water then shaking it via drills to make the sand settle more thickly. First a probe is inserted into the sand below the surface through water filling and vibration. As the probe sinks to its intended depth, loose sand is poured into the opening made by the vibrator probe. Thus a more solid zone of sand is made, enough to support structures.However, vibro-compaction may be appropriate only in clean sand where silt content constitutes only 15% maximum.
In eery peninsula or frond are two rows of residential land or buildings for the awfully rich, and anyone can purchase his place there. Palm Jumeirah is expected to have 120,000 residents and laborers, plus a different 20,000 tourists each day. So it is not really a small island where privacy can be obtained, but a colossal self-sufficient sub-urban area of the truly, really billionaires. There are at present residents living in the islands: real property owners, transients, speculators and workers giving last touches to a few parts of the built up areas. A six-lane highway today functions as the transport conduit in and out the fronds, but in the last stages, residents will also be served by a monorail.
Palm Jumeirah and the three other man-made islands exemplify what contemporary engineering supported by so much money can do. While land building from the sea to make islands may not be a new idea since it has been made many instances before, the project’s enormous size causes it so.
Connor R. Sullivan recently met with a skilled geotechnical consultant for an engineering project he is working on. He hired a couple of skilled geotechnical consultants for a new project. Get a totally unique version of this article from our article submission service
