摘要：
Pb<sup>2+</sup> and Cd<sup>2+</sup> in leachate were adsorbed on clay-solidified grouting curtain for waste landfills with equilibrium experiment. The cation exchange capacity was determined with ammonium acetate. And the concentration of heavy metal cations in leachate was determined with atomic absorption spectrophotometer. Their equilibrium isotherms were measured, and the experimental isotherm data were analyzed by using Freundlich and Langmuir models. The results show that the adsorption capacities of the heavy metal cations are closely related to the compositions of clay-solidified grouting curtain, and the maximum adsorption appears at the ratio of cement to clay of 2:4 in the experimental conditions. At their maximum adsorption and pH 5.0, the adsorption capacities of Pb<sup>2+</sup> and Cd<sup>2+</sup> are 16.19 mg/g and 1.21 mg/g. The competitive adsorption coefficients indicate that the adsorption of clay-solidified grouting curtain for Pb<sup>2+</sup> is stronger than that for Cd<sup>2+</sup>. The adsorption process conforms to Freundlich's model with related coefficient higher than 0.996.

摘要：
The pseudo-dynamic earthquake response test of half-scale specimen of concrete perforated brick masonry building has been conducted. In this paper the dynamic response and the failure mechanism of the building under earthquake action are studied. The horizontal bearing capacity and the damage degree of the test model are analyzed. Finally, the seismic behavior of this structure is evaluated.
