Post-Compaction Sinkholes in Calcareous Fill: Observations and Possible Causes
Reclamation lands have been widely evolving worldwide in the last decades especially in the Arabian Gulf where major reclamation fill projects were developed. This paper focuses on some projects that took place in United Arab Emirates (UAE) which is considered to be one of the leading Gulf countries in reclamation projects. Most of the reclamation projects in UAE were done in water depths ranging from a few meters up to 20 meters. The fill material composed mainly of shelly carbonate sand, with fine contents limited to 10%. Vibro compaction (VC) technique was used in most of the projects to improve the deep fill material and was combined with surface compaction of the top 1 to 2 m. In a recent project and after completion of deep and surface compaction, subsidence cases started to appear with different sizes that varied from minor surficial depressions up to sizable sinkholes with a depth up to 2.0 meters. This paper provides an overview of projects that were constructed in the same area using similar material and reclamation techniques. The paper attempts to identify possible causes that contribute to the formation of these depressions/holes.
