Abstract

Collapsible lands are generally found in arid and sub arid areas. These kinds of soils that are in metastable structure have high void ratio and low weight per unit volume. Loess soil that are wind deposits, residual soils, soils that are formed by volcanic ashes, alluvium soils, fine sand and silts, silt sand and loam are among the soils that have collapsing tendency. Collapsing that happened due to the increase on the water content of the base soil is generally seen in loosen silt layers that have low water content, alluvium soils and in soils filled with sand and pebbles. Significant collapses may occur in buildings constructed on these kinds of soils without any precaution when the soils are wet. In this study the reason of the damage in reinforced concrete storage tank with 25 000 cubic meter volume belong to Konya KOSKI (Konya Water and sewerage services) that was constructed on collapsible soil without taking any precaution and had important collapses in its foundation during the test filling was searched. In order to prevent the possible future deformations in the storage tank and make it possible to use the tank again the soil is stabilized. For this purpose, it was thought that it would be both economic and practical to fill the foundation base of the tank with water from drainage system and fill the volume with water gradually to stop the collapsing. The idea was applied. There were many damages in the tank during the first usage and stabilization with based soaking. These damages were repaired with a strengthening project and the tank has been being used since then.
