Abstract

Saudi Arabian is a vast peninsula with varying surface and sub-surface geology. There are many regions, especially near the eastern and western coasts, where the sub-surface soil is very poor. In these regions ground improvement is inevitable. The case in point is a Beach Structure Complex built along the famous Half Moon Bay Beach of Al-Khobar in the eastern coast of the Kingdom. The geotechnical investigations revealed poor soil condition and suggested use of Stone Columns for improving the ground condition. A total of 3119 Stone Columns were installed under five important buildings by means of Vibro-Replacement Techniques. The performance evaluation of the improved ground was carried out by conducting a number of Pre and Post-Penetration Tests and full-scale Plate Load Tests. The facilities upon these improved grounds are now up since past two years and performing satisfactorily. The focus of this paper is the Case Study of the problem. The paper also highlights the phenomenal recent construction boom in the Kingdom that has now swelled to more than US$ 200 billion. There is a wide scope of consultancy and contracting in the field of ground improvement, which at present is limited to a few local companies only.

Ground Improvement of a Beach Structure Complex by Means of Stone Columns – A Saudi Arabian Case History
