    RESEARCH OF STRENGTH PROPERTIES OF PESTICIDE CONTAMINATED SOIL

    • Engineering properties of soil will change after contaminated by organochlorine pesticides, and the pesticides also bring risk to the health of people and the environment. Recently, the research about pesticides contaminated soil mainly focused on the remediation of the site, seldom on its engineering properties. In this paper, organochlorine pesticide contaminated soils with different pesticide concentrations were made, unconfined compression strength(UCS),permeability test were done at curing time of 1 day, 7 days, 28 days, 56days and 90 days. The test results show that UCS of organochlorine pesticide contaminated soil decrease with the increase of pesticide concentration, UCS first increase then decrease with the increase of curing time, at the time of 56 days reached its peak; permeability coefficient of the contaminated soil decrease with the increase of pesticide concentration, increase with longer curing time.
