摘要

[目的

]

分析上覆碳酸盐岩红土对磷石膏入渗特性的影响机制，为西南喀斯特地区磷石膏堆场合理处置及利用提供科学依据。[方法

]

通过室内扁平土柱入渗试验研究3种磷石膏容重(1.2，1.3，1.4 g/cm

)和3种上覆土层厚度(0，6，12 cm)对磷石膏水分入渗过程的影响，并通过改进的分层型Green-Ampt模型进行入渗过程数值模拟。[结果

]

①6和12 cm覆土厚度处理下水分入渗到底部的时间差异不显著(p＞0.05)，而在0与6 cm、0与12 cm覆土厚度处理下入渗时间差异显著(p＜0.05)。覆土厚度为0 cm的初始入渗率、平均入渗率和稳定入渗率显著高于6，12 cm的初始入渗率、平均入渗率和稳定入渗率(p＜0.05)，稳定入渗率随覆土厚度增大而显著减小。6，12 cm覆土厚度累积入渗量差异不显著(p＞0.05)，其余覆土厚度之间累积入渗量差异显著(p＜0.05)。②相同覆土厚度下，磷石膏容重对初始入渗率、平均入渗率和稳定入渗率的影响均不显著(p＞0.05)。③湿润峰深度实测值与模拟值决定系数(R

)变化范围为0.951～0.995，均方根误差(RMSE)为12.174～40.856，平均绝对百分比误差(MAPE)为0.070～0.227。覆土6和12 cm时，累积入渗量实测值与模拟值决定系数(R

)变化范围为0.963～0.999，均方根误差(RMSE)为1.471～11.201，平均绝对百分比误差(MAPE)为0.046～0.169。[结论

]

磷石膏覆土与未覆土的土壤水分入渗特征存在显著差异，改进的分层型Green-Ampt模型能够用于模拟上覆土层条件下磷石膏的入渗过程。

Abstract

[Objective] The influence of overlying carbonate red soil on the infiltration characteristics of phosphogypsum was analyzed in order to provide an scientific basis for the rational disposal and utilization of phosphogypsum storage yards in southwest karst areas. [Methods] The influences of three phosphogypsum bulk densities (1.2

1.3

1.4 g/cm3) and three overburden thicknesses (0

12 cm) on the water infiltration process of phosphogypsum were studied through an indoor flat soil column infiltration test

and the infiltration process was numerically simulated using the improved layered Green-Ampt model. [Results] ① The difference in water infiltration time to the bottom between the 6 cm and 12 cm soil cover treatments was not significant (p>0.05). However

significant differences in infiltration time were observed between the 0 and 6 cm treatments

as well as between the 0 and 12 cm treatments (p<0.05). The initial infiltration rate

average infiltration rate

and stable infiltration rate of the 0 cm soil cover were significantly higher than those of the 6 and 12 cm soil cover (p<0.05)

and the stable infiltration rate decreased significantly with the increase in soil cover thickness. There was no significant difference in cumulative infiltration between the 6 and 12 cm cover soil thicknesses (p>0.05)

but there was a significant difference among the other cover soil thicknesses (p<0.05). ② For the same cover thickness

the influence of phosphogypsum bulk density on the initial infiltration rate

average infiltration rate

and stable infiltration rate was not significant (p>0.05). ③ The coefficient of determination (R2) between the measured and simulated values of the wetting peak depth varied was 0.951—0.995

the root mean square error (RMSE) ranged was 12.174—40.856

and the average absolute percentage error (MAPE) ranged was 0.070—0.227. When the soil was covered at 6 and 12 cm

the variation range of the determination coefficient (R2) between the measured and simulated values was 0.963—0.999

the root mean square error (RMSE) was 1.471—11.201

and the average absolute percentage error (MAPE) was 0.046—0.169. [Conclusion] There were significant differences in soil water infiltration characteristics between phosphogypsum-covered soil and uncovered soil

and the improved layered Green-Ampt model could be used to simulate the infiltration process of phosphogypsum under the condition of overlying soil.
