Abstract

Jizan city is located on a salt dome surrounded by low-lying flat terrain consisting of silty-sandy soils. Being on the sea-shore, water immigrates to the surface leaving a salt crust on the top surface, which is known as 'Sabkha' soil. This salt bearing (saline) soil and the salt dome affected the foundation performance in the area. Buildings are experiencing foundation problems as a result of the low bearing capacity of the 'Sabkha' soil and the dissolution of the salt rock underneath the footings of the low-rise buildings, causing tilting of such structures. This paper would present the geotechnical aspects of the area concentrating on the foundation design and construction practice. Remedial aspects would be discussed to improve the performance of foundations.

Foundations on Salt Bearing Soils of Jizan

St. Louis, Missouri

Jizan city is located on a salt dome surrounded by low-lying flat terrain consisting of silty-sandy soils.

This salt bearing (saline) soil and the salt dome affected the foundation performance in the area. Buildings are experiencing foundation problems as a result of the low bearing capacity of the 'Sabkha' soil and the dissolution of the salt rock underneath the footings of the low-rise buildings, causing tilting of such structures.
