摘　　要：应用GPR对几种典型的复垦土壤的水分含量进行了测量,研究选择了三种典型的复垦土壤:加入5%的污泥;接种菌根;加入10%的粉煤灰。雷达数据采用宽角法(CMP)测量,对雷达数据计算的结果与重量法测定的结果进行了对比分析。结果显示复垦土壤的介电常数与水分含量间存在明显的函数相关性,说明应用GPR测定复垦土壤的水分含量,在方法上是可行的。但用不同方法处理的复垦土壤,其介电常数与水分含量间存在不同的函数规律。The purpose of this paper is to measure water content of rehabilitated soil using ground penetrating radar (GPR). Three rehabilitated soils treated by different methods were selected in this experiment. The treatments correlated to them are: (1) adding 5% slurry (2) adding Mycorrhiza;(3) adding 10% coal fly ash. GPR data were collected by common midpoint (CMP) method. Noise reduction and velocity analysis were applied in the processing of GPR data. The results were testified by gravity method. It shows that there is evident functional dependence between dielectric values and water content of rehabilitated soil, but the function may change for different rehabilitated soil.
