“…The country is generally relatively low-lying, with the exception of the mountainous regions within the northeast of the country, dominated mainly by deposits of Quaternary to late Pleistocene age, including mobile Aeolian dune sands, evaporate deposits, and marine sands (Cherian 2018). Dubai is situated towards the eastern border of the geologically stable Arabian Plate due to the presence of rocks and separated from the unstable Iranian Fold Belt to the north by the Arabian Gulf (Macklin and Gaba 2009). The ground conditions comprise the horizontally stratified subsurface profile which was complex and highly variable, because of the character of deposition and also the prevalent hot arid weather conditions.…”

Most of the construction standards and project specifications allow using higher resistance factors once geotechnical design parameters are estimated through static pile load test results. Instrumented axial load tests are performed to verify the pile design and to provide valuable information to permit an economically feasible redesign. Bi-directional static load test (BDSLT or O-cell test), an innovative load test method, performed simultaneously in two directions; adopting sacrificial hydraulic cells was used frequently in the Middle East and the global foundation industry. This paper presents the performance of two preliminary instrumented bored cast-in-situ friction test piles of 1000 mm (PTP1) and 750 mm (PTP2) by BDSLT using sacrificial hydraulic jacks, socketed in the Sandstone and Calcisiltite of the Business Bay Project, Dubai. The test piles were instrumented with 4 levels of vibrating wire strain gauge technology and were load tested to determine the pile-rock interactions within the various segments of the piles. By using Eurocode 7 procedure, the characteristic compressive shaft resistance of piles was determined from the test results to optimize pile foundation design. The results have led to a reassessment of the piles and barrettesinitial pile design to quantify the geotechnical parameters precisely to execute an economically sustainable project in Dubai.

“…These rocks laid down in a various deposition, principally shallow marine, intertidal, fluvial environments and sabkha [31]. These rocks have also been affected by relatively limited deformations associated with the anti-clockwise ongoing movement of the Arabian plate towards the Eurasian plate [32,33].…”

Inferring the Creep Settlement Behavior of Rockfill in Reclaimed Lands by Advanced SAR Interferometry and Numerical Modeling: An Example from Arabian Gulf

Satellite Advanced Differential Synthetic Aperture Radar Interferometry (A-DInSAR) is becaming a key-technique for monitoring ground deformations. The potential of A-DInSAR for settlement monitoring is exploited in this paper through the investigation of a reclaimed land in Dubai (UAE). Time histories of displacements were obtained from COSMO-SkyMed satellite images over the period between 2011 to 2016, allowing to derive the long-term deformation of the entire artificial island. Special attention was paid on long-term settlement of the hydraulically-placed rockfill of the peripheral rubble-mound revetments. The A-DInSAR results have been compared with results derived from numerical analyses and with field surveys, proving the relation between observed and modeled displacements. The study has also revealed that rockfill long-term settlement (creep) rate is significantly dependent on the aging (time since placement). In the analyzed time-frame (2011–2016) it has been observed that recently placed rockfill experienced creep rate up to ten times higher than the creep rate measured for similar rockfill structures placed 30 years earlier. Furthermore, it has been demonstrated that static compression by preloading and dynamic or impact densification induced by wave forces proved to have also a significant impact on reducing the creep rate of the rockfill.
