Abstract :
In this work, the effects of water and oily water leakage on the soil characteristics in the industrialcomplex such as refineries are investigated. In a real case study, the leakage from cooling waterpounds in Bandar-Abbas refinery in south coasts of Iran is investigated. This refinery was built about14 years ago and recently the evidence of leakage from pounds has been observed. A fieldinvestigation program with ten bore holes around the water pounds in the refinery has been carried outto inspect the effects of leakage on the soil and scouring of it. The main soil mechanic characteristicssuch as the result of Standard Penetration Test (SPT), soil dry density and humidity percentage arecaptured in the field and laboratory investigations. It is concluded that the depth of affected soil byleakage is about 5 to 6 meters. The leakage is especially occurred in the east side of the pounds. Thebest way to prevent the leakage and to improve the affected soil characteristics is selected based on thesoil mechanics data. The grout injection in the regular pattern all around the water pounds is assignedas the applicable method to cease the leakage and to improve the soil stability.
