酸、碱污染土的试验研究

With the rapid development of national economy, the small environment problems have been paid more and more attentions, particularly the problem of polluted soil. The control of polluted soil has great significance for the environment protection and the civil construction. Through the laboratory experiments, the research on physical mechanics property of soil polluted by acid and alkali has been done. The result indicates that the influences of acid and alkali on soil are different. Compared with ordinary soil, some parameters of polluted soil, such as mass, specific gravity, liquid limit, plastic limit, porosity and compressibility factor, have been changed. Meanwhile, combined with the variation of mineral composition and microstructure after the soil polluted, the causes of the change for physical mechanics property were explained.
