Abstract:
In order to study the collapsibility features of saline soil, under the optimum moisture content condition, the different content sodium chloride is added into the natural saline soil. Through the centrifugalize model test inside, the influence of different content chloride ion and under the same chloride ion salt content the different temperature to the coefficient of salty soil are researched. The research indicated that along with the added chloride ion mass ration is: 3.48%, 5.31% and 9.59%, the coefficient of dissolves to sink at first increases to 0.83% and 1.65%, then reduces to 1.58%. The influence of temperature on the coefficient of the dissolves to sink of salty soil caused by chlorine is little. The concentration and time curve, the relationship between concentration and filtrate are in line with the power function curve. 5 tabs, 8 figs, 10 refs.
