A Study Of the Effect of Soil Movement on the Failure of Oil Tanks Foundation in Khartoum North Area

Abstract

Many Studies on oil storage tank foundation systems have shown that stability and soil movement are the two main factors which may lead to the rupture or even complete failure of oil tanks. Tank foundations are of variable types they are considered as special structures which required special institute (A.P.I.) and British standards (B.S.). In this study oil tanks foundation problems caused by: soil mechanic and method ology of construction were investigated. As a case study: oil tank foundations in Khartoum north (KRT.N) area were considered Available experimental data was collected to identify the mechanical and chemical soil properties the depth of foundation necessary for stability and soil bearing capacity (B.C.) These are the essential factors for foundation design. Questionnaire was carried out to indicate the actual implementation practice of oil tank foundations, design and construction. Data drown from the questionnaire was analyzed statistically using (S.P.S.S.) Based on the two studies conclusion and recommendations are presented, a complete and acceptable identification of the necessary soil properties for adequate oil tank foundation design and construction was achieved.
