摘　　要：介绍了Arya-Paris预测模型的基本推导过程。选取广东肇庆地区的花岗岩残积土进行了室内颗粒筛分试验。通过压力板法,得到其土-水特征曲线。将拟合得到的土-水特征曲线与采用室内试验测得的土-水特征曲线进行了对比。研究结果表明:采用Arya-Paris模型,预测花岗岩残积土的土-水特征曲线的可靠性高。预测并得到了不同干密度下花岗岩残积土的土-水特征曲线。The basic derivation process of Arya-Paris prediction model is briefly intro- duced. The granite particles in Zhaoqing city of Guangdong province were selected and the indoor particle screening curves were carried out. The soil water characteristic curve was measured by the pressure plate method. The fitted soil water characteristic curve was compared with the soil water characteristic curve measured by laboratory test. The results showed that the Arya-Paris model had a high reliability for granite residual soil and the soil-water characteristic curves under different dry densities were gained.
