الملخص الإنجليزي
The construction of many major projects is located on many areas of gypseous soils in Iraq, which present about 20 % of Iraqi land.
In many projects buildings on gypseous soils suffered from cracks, tilting, collapse and leaching the soil, because by dissolution of gypsum.
The collapse of gypseous soil can be divided into two types, first, the soaking collapse, which is caused by soaking the dry soil or partly saturated soil with water, and under specific pressure, without flow of water, second, the leaching collapse, which caused by flow of water through the soil under any specific.
The major purpose of this research is to investigate the leaching collapse and permeability of gypseous soils.
Undisturbed block samples of a gypseous soil were obtained from Al-Tharthar area, Iraq.
The gypsum content was found to be about 75%.
An experimental investigation was made through carrying out several series of tests on these samples.
Also, a series of leaching tests were carried out using special oedometer cells at different stresses.
Results of leaching tests showed that the strains due to leaching would be higher if the OCR equal to 1.
When the OCR exceeds unity, an increase in void ratio occurs and leaching strains become insignificant.
