1. the physico-mechanical properties test method of an acid pollution soil is characterized in that this method comprises:

  • (a) the undisturbed soil test block is soaked in the following way to obtain acid pollution soil;

    Adopt the sulfuric acid solution of same concentrations that different time is soaked in described undisturbed soil test block;

    Adopt the sulfuric acid solution of variable concentrations that the identical time is soaked in described undisturbed soil test block;

    (b) afterwards the acid pollution soil of above-mentioned acquisition is carried out the physico-mechanical properties test respectively, comprising;

    water percentage, soil sample density, the test of circular cone embedded depth, miniature vane shear test, direct shear test, consolidation test;

    (c) institute'"'"'s determination data in the recording step (b) reaches according to described record data and makes;

    The physico-mechanical properties of acid pollution soil and pollution time relation curve;

    The relation curve of the physico-mechanical properties of acid pollution soil and sulfuric acid solution concentration.
