The paper mentions in a real problem happened in the dumping ground, the industrial activity area or coastal area, that is the contamination of pollutant in the ground. The ground contaminated by seawater or chemically polluted water will lead to the changes in construction characteristics of the soils. The testing on influence of waste water on soil deformation was carried out on loess soil and clay paste when they were saturated with pure water, crude oil and detergents. The change of parameters especially compressibility of loess and clay paste when these soils were saturated by pure water, salty water and detergents had been investigated. Besides, undisturbed clayey samples were also tested in saturated condition with salty water. The results of the tests show that the soils saturated by detergents will increase their deformation and compression, however, they become inversely in case of soil saturation by crude oil. When soils saturated by salty water, the change of their parameters is on contrary depending on soil’s mineral composition. |
